So who wants their ECU's "Chromed"?

[Jesters Deadd]

I enabled bit 2 of periphery 0, now the trims are cycling like they should....BUT the car still has startup problems. 7 times out of 10 I need to unplug the injector resistor pack to start the car. It seems like its more of an issue on hot starts than cold starts. I have 2 sets of latency values for the same injector (delphi 1000cc/pte1000cc). I'm gonna trying switching the values to see if it helps. Also going to monitor fuel trims.

I had to change the published latency values for my rochester/pte 1000cc injectors to get my car to run right. Try these.
3.825
3.39
2.31
1.5
1.05
0.69
0.45
Even with the stock start up tables it ran really good. With the start up tables fix with gregs advice it starts super!

The car runs well...just gives me a hard time on startup. I tried your latency values and immediately I noticed that my car was running worse so I switched back to the PTE values. I'm gonna drive around with the PTE latency's and see where the trims settle. Then I'll switch to the Delphi values I found online and see what those do.

Greg, Thank you VERY much on editing the startup tables. I've flashed the rom back to my car and lets see how it runs...

My car won't start after I swapped to a 482 Maf. My settings are correct. That leaves only the Maf or the adapter harness as the problem. Anyone care to test my Maf in their car if I send it to you? I'm in the middle of Kansas so a local person running an EVO Maf on flashtune (needle in hay stack I know) would be best. :/

Well, nevermind.... Put the old Maf in and still won't start. I have other problems...

Lesson of the day: expect fouled plugs when you have no Maf plugged in to flash ecu with car running...

So I have a question, with the Maf unplugged did the ecu try to make the car run as if it had 360 injectors or the 550s that are actually in there?

Jeff lives in Kansas.

It ran the injectors at a fixed IPW based on RPM and TPS. It forgets the entire fuel calculation routine and just opens the injectors based on this single table.

Great to know. Thanks! I changed the front 3 and it kicked right off. I'll get the rear bank in and swap back to the 482.

Hello Greg. I saw a post from you at the other 3s site about running a "zeroed out" gm maf and blow through along with flashed 99 ecu.

What would be the loss/difference compared to running a evo8/9 maf? Positive/negative aspects. I ask because I might want to lose the bubble and run rual filters. Thanks for sharing information.

If you read that post you should have seen my comments about the issues it had on Toni's car.

Ops sorry. The answer was right there. I'll stick with the evo maf then. Might make the swich if you guys find a good solution with the gm maf. Thanks!

any update on the V2

Was having problems with the boost gauge mods so I've decided to omit them from V2 for now. Also been slowly plucking away at the manual.

Most of my beta testers (and myself) have put our cars away for winter so that concludes the beta testing. All the wait now is on me to get this manual finished.
