I don't think you will be sorry. And Mike makes a great looking harness. Trust Lextech also, he knows what he is doing.

This swap is a great way to go for third gen owners. I have tuned every car that has done this swap at Akron Horsepower and they have all made great improvements over the old system. Mkos's fromula was one of the first and mike at EFIconnection has brought many other costumers to our shop for there dyno tunes. This is the wave of the future. These computers have so much more to offer as far as the tune goes and can handle boost and NOS. Everyone should be doing this swap if they want the best to offer for therer cars.

Does the 2001 Express Van software and the 411 computer have an output to control the egr valve on a TPI motor? I need to have the smog equipment working here in California.

scuzz

I know it's implimented in the 0411 cal, but I'm not sure how to get it to control the TPI stuff.
Maybe S10Wildside will know.
I had to disable it in my 41 Chevy pickup project.

Mkos1980

I bet you can almost have a fake wire if need be. My car along with Erins SC car both passed perfect with just cats. no canister, egr or smog stuff. I have 25lbs injectors and Erin has 42's. It accually burned super clean

Thanks guys. I would hate to spend all the money for the conversion and not pass smog. I will be installing a 4L60E transmisssion and I only have two choices for control. The TCI controller or the 411 ECM conversion. Maybe a GM controller as a third choice.

Lextech

The 0411 will not control the TPI type of EGR. The codes can be fudged via tuning. My 98 GMC passed with no cats, no EGR, Ramjet intake, No post cat O2s, and 2 turbos, and 42 lb inj.

Mkos1980

Jamy and I just tuned mine again with the built 700R4 and Edge converter. We picked up 30RWHP and 38LBS tq putting us at 355rwhp and 364rwtq

1989GTATransAm

Good numbers and with an A4 no less. Do you have a high stall and was it locked or unlocked?

Mkos1980

2600 and it was locked. Unlocked the numbers were 339RWHP and 330RWTQ. It really made the TQ numbers run up. We are thinking about enabeling in the PCM to keep the converter locked under 2nd, 3rd and 4th under WOT. Although not "best" for the converter, I am sure it would be fine assuming the quality of the converter. We locked the converter up in 3rd at 2K and did the run.

1989GTATransAm

Your dyno results are virtually identical to mine. Interesting with the unlock an locked results.

S10Wildside

Matt - What's the part number on that Cloyes timing set? There's several available. Do you have the number? I want to get and compare that set to the GM set.

Thanks

Has anyone besides Craig tried to use a small spacer/shim in between a double roller chain and the reluctor wheel???
Craig said it might only have to be about .100", but just enough to clear both the chain and the timing cover.
I need to also take a look at a Vortec style distributor to compare it against the std. SBC one....it sounds like I just need to see how to adapt the sensor and the cam reluctor to the std. distributor.
There's hope that I will be able to use my comp cams double roller and MSD dist.!

badgta

lets us know bro.. i have a cloyes true double roller.. i really like their products and want to keep it......

hey s-10, if we are able to do a group purchase for your harnees, how much would ya knock off?

thanks

1989GTATransAm

I have been looking into the spacer myself. Like you I do not want to replace my timing chain as I have everything dialed in. Whether the spacer is .150" or .200" you need to take the same amount off the balancer.

Mkos1980

my only concern would be the ring coming to close to the front of the cover

Craig Moates

I think that was right. Maybe we tried 0.200" and it was too much. Backed off to maybe 0.150"? Can't remember for sure. So long as you have 0.030" or so clearance off the chain it should be OK.

I'm pretty sure it was 0.150". Took that much, plus a little for the reluctor thickness I think, off the balancer. Yeah, 0.200" off the balancer, and 0.150" shim behind the reluctor.

With the plastic cover, I figure it'd wear in a little if needed ;^).

Been driving the 383 Tahoe a bit with the new built tranny and 2400 vigilante, it's a monster. Out of fuel pump now (won't respond to more VE up top), so time to throw some more parts at it (li'l Walbro 255). Oil leak around the valve cover also, must fix ASAP. Gears and posi are next.

S10Wildside

I suppose 5-10%, depending on the quantity ordered. Comparing these harnesses to other manufacturer's LS1 harnesses, the prices are already far less. There's not much room to work with.

vernw

I think your prices are great as they are now.....

koolctk

I read what was needed on the EFIconnection website to make this PCM work. How would someone pass smog in CA as 1989GTATransAm asked before?

And Personally you should sell the stuff as a kit needed to convert a regular gen I block with instructions and all (unless you did and I missed it) ? I want to do a 383 TPI w/ spray but OBDI blows and I wont use it.

And whats the total cost parts wise to have the harness and PCM in and ready to go (approx.)?

Mkos1980

If a kit was to be used and all parts sold new, The price would be huge. Its best to find the coil, ignition module as a one piece unit already on ebay + finding the new parts on ebay as well and so forth. If you wanted all new top of the line, it would probebly be 2K assuming a new pcm, performance distributor, all new sensors and so forth without ebay.

S10Wildside

I'm trying to line up a 3rd gen Camaro to do this conversion and take detailed pictures of the conversion. I may have a car lined up. I've got a nice 400hp motor ready and a low mile 4L60E. This is pushing back the coil pack setup project, but I can only focus on one thing at a time and I think detailed instructions on this conversion is necessary before coil packs are introduced.

I'm bummed that the coil pack setup is getting pushed further back, but sometimes that's just how it goes.

koolctk

Anything for people who have to deal with smog? is this still useable with EGR etc.?

S10Wildside

Not yet. The LS1 PCM does control EGR, but not the TPI engine type.

koolctk

Any thoughts/ideas to get it to pass CA smog? Does the EGR need to actually work, or just need to be there?

Mkos1980

It just has to be there. You can pass with it "fake" connected. I passed with just a cat nothing else. Same with the blown car.
