Welcome to the next installment of the

Topic of the Week
(revisited)
to run from 4/19/02 to 4/26/02

The subject for the week is all about Winaldl, scan tools, programming eproms

How many of you have seen winaldl in action? It costs $5 in parts to build and you can use any laptop that has windows installed!
Even if you have no idea what half the stuff is you still can monitor the sensor data, the flag data, and the error codes. Then if there is a problem just data log and post the information on the board.
Even if you don't have a laptop you should still build the cable and borrow a laptop every once in a while.

I have all the parts for it, I just need to build it

Chuck!

Ive used it, its just not too interesting on a stock engine.

Wait for summer though.. it'll be my new best friend

I've got an ALDL scanner, but I've never used WinALDL. The damn ALDL on our cars is so slow. One data read every second or so just doesn't cut it. The TPI cars get a nice clean graph when they plot out their ALDL reads...bastards.

I need it bad...this tuning is kickin' my butt.

WOT is great but cold loop and some of the cruise are not where they need to be

I need a laptop. I've been trying to find a used one that does not look like overpriced junk.

How do you build the cable?? Where do you get the software? I'd love to see what's happening in that little metal box of mine that controls the engine!!! Does it require a seperate program for TBI & TPI, I own both.

It's one of many tools used to make your life easy...only difference between this software and other scan tools is that it uses a computer and is freeware, just build the simple interface hardware. You can see if the engine is having to add fuel, take away fuel, what the sensors are telling the ecm ETc.
It's a must for getting that extra hp out of any modified TBI vehicle.

I have the WINALDL, but I still need to build the cable, and buy a laptop. I'd also like to start burning custom e-proms.

My question is, What all do I need to burn proms?
Could someone post a check list of all the necessary hardware and software needed, and if possible, places where they can be purchased, and possible prices.

Thanks,
Mike

WINALDL is great! Jonas is someone well respected in my book and I haven't even met the guy. Works well and has helped me a lot. Will be instrumental in my MFPI 7747 system, which I have just decided to continue, with the new XE269HR Comp Cam I just got today, 218/224 112 lobe sep, like .495"/.505" lift.

I need someone to burn me a chip or two, though, ASAP. I will provide the CHIP and BINs and ??? Anyone help me here? Cannot wait for the CA turnaround.

You don't even need a laptop. Just put some old junk Pentium in your garage with a screen from a garage sale. Its been said before that the cable can be up to 80 feet long.

for those who are building the cable, just go out to radioshack... They cary all teh parts needed to buil it. Just solder and go... It only takes about a max of 25 mins or so to solder it up...

I second Tas. Any old computer capable of running win9x can do winaldl. Just keep your eyes open... I managed to get a nice toshiba techra laptop w/ 15 inch screen 10 gig HD and pII proc. for under $300. Just frequant pawn shops and eventualy youll find something.

JPrevost

I got my p75 IBM thinkpad 755cx for $50 online. Then I bought a dc/dc converter for it for another $40 then $10 for 8 more mb of ram and I think I only spent $10 on the 10/100 PCMCIA network card. I didn't need the network card or the ram so figure I spent $90 on my laptop.

PaulD

I would be extremely interested in learning how to make my own chips. I just don't know how, where, what to start. Anybody that knows in New England interested in teaching and showing the rest of us?

kevm14

Paul, are you running the stock ECU (and PROM)? If so, do you know what the # is? I'm curious what our number is...

Lionsden

Winaldl rocks :rockon: I was in on using the first version(.98).

burntblues

I think that everyone knows where I'm going with this post...

anyway for someone to write say a manual or guide for winaldl with

1.explanations and definitions
2.acceptable levels for every sensor
3. ways to tune sensors
4.ways to adjust each thing via a new chip.

I'm going to be getting the burning software as soon as I'm done with school, so if I already had the info it would be ten times easier. I've read the articles online about the stuff but they all neglect acceptable levels and pretty much only offer a description of sensors. I know its a bunch of work for someone but it would put all of us on an equal playing ground and cut down on the unnecessary requests for info that frustrate so many members of the board.

Ya, I'm kinda in the same boat. I want to start burning chips one of these days but I wonder what is normal for some of the values.

brharris27370

I have a little Toshiba P75 laptop with Win95 and 16megs of ram, 800 megs of HD. NO BATTERY so you will need a DC to AC converter. ($40 at www.harborfreight.com) $80 including shipping for it. I don't remember if it has a modem in it or not. I will at least scrounge up a 28.8 or maybe a 33.6 for it. Email brian@bharris.org

That guy will make u the cable and guarntee that it works for ur application for 29 bucks shipped if u use money order. I figured I would save myself the hassle and do it that way.

Tas

is there a writup on how exactly to make the cable step by step? Just looking at the diagram isn't good enough. I wana see each part, the discripton of it, and possibly Radio Shack part number.

kevm14

The cable, or should I say connections, doesn't look like it would be that hard to make. The hardest part would if one were to desire an OEM-style plug that can be removed from the ALDL at will. Otherwise, it could be hard wired into the ALDL. Q though. Does WinALDL report error codes along with all of its other magic? If not, I don't know if I'd want to hard wire it. My XP240 would still be good for that.

When I get some time, I will give you some part numbers on what's required to build it. As a third-year ECE major, I don't have a problem reading the schematic. It's just the logistics that would hang me up...

Does anyone know what block learn actually means? i never did find out what it actually represents...

dimented24x7

iTrader: (2)

kevm14, it does return error codes.

burntblues

from what I've learned BLM is the chips ability to adjust to certain deviations that the engine makes to return the air/fuel back to 14.7. Am I right?

-=-Mike

kevm14

Wow, so theoretically I could ditch my $95 XP240? Damn. That thing is great, I use it ALL the time. I'm serious. I'll be out driving with a friend or two and randomly turn it on and scan through all the values to see how it's running. Even if I'm actually going A-to-B I'll do it. And it's on the same fancy energisers I used when I got it a month or two ago.

As for block learn - yes, I know what it means. Block learn, aka BLM, BL value, Long Term Fuel Trim refers to the relative level of the values in the fuel tables in the ECU. 128 is the nominal value and supposedly refers to an air-fuel ratio of 14.7:1. A higher than 128 value means the ECU is adding fuel in that location in the table (MAP vs RPM). I think it compares to "stock" or the values in the PROM that it starts out with when you reset the ECU. So if you change those values, 128 doesn't mean what it did before, but that's ok, as long as you know what's going on.

You didn't ask, but I'll explain anyway - the integrator is the compliment to the block learn. It indicates how the BLMs are CURRENTLY changing. The integrator shouldn't be off 128 for a very long time - if it goes above 128, the BL values should change and shift the integrator down until it's 128 again, then the BL values stop changing...

ahhh... thanx.

PaulD

Dang Kev, glad to see you're learning something useful. Do you think you could learn how to burn the chips? You could become my new best friend.

I should have gone EE.

kevm14

I am definately looking forward to burning my own PROMs. I understand the process of burning (though I've never actually done it before) and I understand most of the tables and constants in the ECM. I think I will need to burn PROMs when I put the LT1 cam in. So I'll learn out of necessity, but also interest.

winALDL uses the pin E which is a 160 baud syncrhrnous o/p mode ... ive used this on my 89 v6 also u can use pin M which is the 8192 assync mode which is a lot faster ....there are some other circuits i built for the 8192 and good thing about that is that dos software is also availabel for that so that ur laptop doesnt have to be state of the art...

160 baud .20 -25byte = refresh every second

whereas teh 8192 refreshes 8 times nearly im not sure though eveyr second but u can definitely see the difference ...

so bottom line is if u have a M pin in ur ALDL connector go ahead and build the ALDL cable fro 8192 baud

Grumpy

While it's still undergoing R+D, all the answers about a faster ALDL are to be answered.

If you peel open an ecm you'll see an edge board connector on one end. You can read the processor's ram from there. There's alot more to it then that, but in a nutshell, there is another option being investigated.

If you go to www.chuengineering.com and poke around you'll see one application of the edge board technology. Just Kent isn't interested in explanding his product line.

JPrevost

Grumpy, I've e-mailed him a couple of times. At first I thought it was for the 7747 but then after a couple of e-mails I figured it out. He said that he would change the software so long as the hardware is all the same!
Wouldn't this just be a software problem?
If so, I think I can get him to expand his development, especially if it gives him buisness from all the 7747 and 8746 guys.

burntblues

Has anyone been working on that "manual" for winaldl with explanations and acceptable ranges?

Just wondering,
Mike
