What will we have to do to datalog through the ECU with a 165 ECU? Will this be compatible with Mike Davis Hack?

I already have pinned a new wire to D8 of my ECU as per Mike Davis....

 

thought i might give the rest of you something to look over and think about . . .

Anone got theirs up and running yet?

 

just got home from a week in NYC. Will send payment in the morning. Thanks guys!!

 

Hey guys,

I sent an email to sales@zeitronix.com asking if I could still get in on this GP. They emailed back and said to jump on the wagon... and I did. I just fired off payment via paypal. Looks like this is just about over.

On a side note, I'll be ordering an autoprom from Craig this Friday... It almost feels like Christmas!!!

 

Btw...

For anyone who may have missed this GP, I found another one that's still open here. I was going to use that one if I wasn't able to get in on this one. Looks like it should be open for another week or two.

 

I noticed in the instructions that the RPM input is 0-5v square wave, does anyone know if this is a standard tach signal? can it be hooked directly to the "tach" terminal of an HEI or the "tach" terminal of an MSD 6a?

 

Hey guys, I know this is stupid but I can't figure out how to get the group buy price to show up when I am trying to checkout.It shows full price when I get ready to pay. Sorry. Just let me know what to do.



Nevermind. I got it. DUH

 

I seem to be missing the signal harness. Did that happen to anyone else? I'll e-mail them to send me one.

 

Just got the box from UPS.

What pin on a 165 ECM do I hook the RPM input to?

 

http://chevythunder.com/fuel%20injec...9%20pinouts%20(ecm%20#1227165)

 

I used Mike Davis hack and pinned into D8, now all that's left is to setup TunerPro RT with a lookup table to display it in AFR. Can someone help with that?

 

What is the Mike Davis hack. I thought D8 was unused on the 165.

 

That's right, it is unused and therefore available to someone to use and add to the ALDL stream so it can be viewed and logged via scanners.

Do a search for Mike Davis and you will find the hack, or use AFRTuner (search and you shall find) to insert the hack into your current bin....Must mention I think it's only good for ARAP bin, luckily I converted to ARAP at the beginning.


My question is still the lookup table needed in TunerPro...how do we do it?

 

Hey-

Has anyone hooked this bad boy up without using the wideband hacks? Still scratching my head as to where I pick up the rpm input from. Looked at the '165 pinouts and was thinking of using Pin B5 (distributor reference). Has anyone else done this?

 

It seems to me that the easiest place to pick up RPM would be from the distributor, at the tach terminal. I have yet to determine if this is "0-5v square wave" though. I think I will contact Zeitronix as my web searches have come up empty.

 

Ok, about this tach thing- I emailed Zeitronix and here is their reply;

Zt-2 is equipped with RPM signal conditioning circuitry so you can use almost any RPM representative signal. Here are best choices in order of preference:
Clean 0-5V square wave from the ECU
Tach signal from HEI
Signal from the ECU driving the ignition transistor
Primary (LOW VOLTAGE) side of the ignition coil

Hope this helps,

I will also start a new thread with this info, and maybe we can address questions and comments to the new thread also.

 

Mine didn't come with a signal harness!! Did that happen to anyone else?

I e-mailed them yesterday about it, still waiting for reply...

 

Mine came in with all the pieces,etc.

Does anyone know if the O2 sensor can be stuffed into the exhaust outlet and will it read corectly there?

I'd like to be able to do this without installing another O2 bung or without removing my current O2 sensor and installing this one.

What about it , guys???

 

Should be able to as long as you don't have a cat con.

 

I simply made I pipe that slips over my tailpipe and installed a bung in that pipe. Now I can clamp it on to many different cars in the matter of seconds. This will work for non cat cars.

 

I got mine yesterday- all parts were there in the box.

For the question about "stuffing" the sensor in the tailpipe- I asked the same basic question in a few places, and the best answer I got was to place the sensor in a piece of pipe, and one reply said he had 9" pipe past the sensor to reduce atmospheric contamination. Any little hiccup in the exhaust stream would draw air in, and read a faulty lean condition. I am going to make a similiar clamp on pipe- but I am going to weld in a bung too so I can compare the readings. I wont get a chance to do it until next week or so but I will post my findings if no one beats me to it.

 

Here's Grumpy's setup that I checked out at his last Pow-Wow. Pretty clever if you ask me - just buy a cheap vise-grip and weld it to the pipe! I think it's about a 1&1/2" pipe with a bung welded in.

 

neat. . .
so the above example would only give accurate readings if the exhaust does not have a cat, correct ?

 

i'll post a pic of mine tonight as well

 

For some good general installation info, see the Innovate WBO2 manual here:
http://www.innovatemotorsports.com/s...Manual_3.0.pdf

They specifically say NOT to just stuff it up the tailpipe...

 

ben73, etc......

It seems there would be a lot of dilution of the exhaust stream at the end of the exhaust pipe.
But I certainly don't know......there's a lot of things that seem logical that aren't.....in real practice.....

What is the reason Inovate says not to do this?

 

Arrrr...harrrrrr guys, by Jove I think I 'ave it. I read that pdf posted by ben73.......

The PDF sez not to just cram the sensor up the tail pipe.... it goes on to say you CAN use the optional tail pipe mount... probably v-e-r-y similar to Grumpy's...

The reason not to do the ram it up the pipe deal is the sensor needs a free air reference....
There's the answer.
As long as you use some contraption that keeps the sensor connector outside the exhaust stream there should be no problem.......

NOW,, where's those old vise-grips I used to have....and an old piece of pipe I saw laying around.......

WooooHooooooooo!!!!

 

I just got my zt-2 last night. I can't remember seeing a bung in the box though. Is that something we had to purchase separately????

 

i too didnèt get a bung...but i was sure that was part of the package...I guess it's one way to give a group buy price, just send less parts!!!

Luckily I already had a bing setup from when I borrowed a friends LM1 unit 2 weeks ago.

I still would've appreciated getting the bung in the package because I need to weld one on our bracket racing car that we are finally taking to the track tomorrow!!!!

 

Nope, bung isn't part of the deal. That's up to you to provide (or he can sell you one.) I'm sure you can find one on the 'net somewhere reasonably cheap or maybe even at your auto parts store.

 

Right, I didn't mean to make folks think they were part of the package. Sorry.

02 bungs are just a couple of bucks... Jegs & Summit has them.
Both are fast shippers... last few I got from Jegs.. bout 7 bux if I 'member correctly. AND A FREE YELLER HAT, to boot.

All your local muff.shops have them too.
They would probably even weld one in a small exhaust pipe and weld on your "Stanley" vise-grips also for a couple bucks.

I KNOW you guys aren't going to weld up your Craftsman visegrips....are you? NanerNanerNaner.

I had a bung welded into both my header extensions so for time being I'm going to just uncap the second one and use that to play with the WB02.

 

I got mine hooked up in my 85 Vette with a 165 ECM. This thing is very cool. I used the EST Output (D4) for the RPM input. With the RPM and the A/F ratio it is easy to tune. I used the bung
in the headers to mount the sensor and the simulated narrow band to feed the ECM. It’s about at 9 o’clock. I will see how long the sensor lasts.

Tuning without a WBO2 is useless.

 

Dave,
I'm interested to hear how well the simulated narrow band output works?
Can you post back after you have had a drive with it in place?
Is anyone else planning on using the narrrow band output?

 

It runs just fine. It works like the stock O2 sensor. The A/F is 14.7 when I am idling or cruising. I connected the narrowband output to the user input to see what it looks like. You can't use the narrow band to tune, it's a switch. Bummer.

 

Can anyone help by telling me what pin on my ECM do I hook the RPM input to?

I have a 1992 LT1 Corvette.
Thanks
Arnold

 

crap, i wish i would have seen this a few eeks ago. Im realy new to this tuning stuff and my local dyno guys say that I should really invest in a WB setup. I have a few basic questons before I buy:

Do I need a laptop with this or can I just use the LCD display
What else do I need to buy to use this
How much tuning ability will I have w/ this and my stock 7730 ECM
I am using a Ed Wright custom piggyback chip along with my stock GM one. Will that be a problem. I also plan on buying all the stuffed need to do prom modifiactions over the winter. Will I still be albe to use this WB02 or is there a program out there that will offer me the same tuning capibilites? I just dont want to buy this and then find out that a certain software program has the same thing in it. anybody understand me or did I lose anyone. basically, what I am saying is that I WANT to get into prom tuning and need to know if I really need this WB setup or should I just hold off on it and buy a laptop and a software program instead. I want a way to view realtime data on my car.

 

It looks like this thread has been idle for about a week. I guess if people weren't happy with their Zeitronix units, there'd be some griping up here, so is no news good news?

Someone else mentioned they were gonna post some side-by-side with a borowed LM-1. I checked out both websites and the difference in price is $70. ($279 vs. $349)

I'm just wondering what people have found they like/dislike about the unit. I think I'm going to buy in the next few weeks.

-Dave

 

Chevellefan, I like mine, but I dont have anything to compare it to. Someone else posted that it compared well to the Innovative unit, they were like .2 apart which is within their own tolerances. Check out the other post- there are more opinions there too.

Its fantastic...
I thought my tune was pretty good, but the WB has shown up a number of areas that can be improved..

 

I'm the one that compared it to the LM1.

.2 difference between the two.

Functionality is great. A little cumbersome with the laptop and all, but I already had a laptop in the car for the ALDL scanning.

Really like that you can save the entire "EKG" style view and look at it in more details.

Overall 2 thumbs up!

 

I am very happy with mine. Small and easy to hook up. I have the RPM and TPS hooked up to it. I like using it better than my scanner because it gives you 64 data points per second and instant results. I use the plot with the A/F ratio, RPM and TPS on one graph. Do a WOT run hit the space bar to stop the plot and move the cursor and analyze the results at any point you want without having to open a file or export to Excel.

This thing showed me my A/F ratio was 13.5-14 at WOT. Yikes! Something my stock O2 didn’t do. It only took me two chips and now I am 12.5-13 at WOT.

Another cool thing is you can see when the ECM switches to PE mode. Find the % TPS that corresponds to PE mode of you ECM and you can see the A/F ratio drop into the PE range. I like being able to quickly measure, make a change then re-measure and the new measurement makes sense. Very cool.

 

I hooked mine up at the distributor "white" wire on the ignition module to the coil and routed the wire into the factory loom then into the interior to the ZT-2. Works perfectly. Look at the wiring diagram for your 'vette, I'm sure the LT-1 is probably similar in basic wiring like this. Looking at the Alldata site it is the white wire between pin "D" of the opti spark coil driver and pin A of the ignition coil.
I'm impressed with the performance of this little unit, very functional the various parameters plotted are going to be a super tuning tool. I need to install my EGT sensor and it's done.

 

Thanks for the info. Have it hooked up and running. I would like to hook up the % TPS now; any ideas which wire this would be??
confused:
Arnold

 

Im not sure which ecm your vette has but on my 8746 ecm I tapped pins B5 for RPM, a ppl/wht wire -- Distributor Reference Pulse Input : Hi .
For the TPS it was pin C13, drk blu, Throttle Position Sensor Input.
There must be a pinuot of your cars ecm floating around here somewhere.

 

Is anyone up to try to do a new gb? I will get one.

 

I am...how much are they? Also, will it work with my 85Z28 and my 95Z28? I am getting autoprom with tunerpro and also tunercat to tune the 95.

 

you could try emailing them. i told them that i had missed the gp that ken put together but wanted to buy one right away. they let me have the same deal as everyone else. seem like decent people. now i just need $$ for autoprom and i'm set...

 

I will e-mail the tonight. Hopefully we can get 20 people because I thing there only $240 each which is not bad $40 off if one person got one. I will let you know. Ok I just e-mailed them and waiting for them to e-mail me back. If they say yes I will start a new post that way we can get as many people as we can. I will let you know
