yeah brake switch works and it unlocks the TCC.

so after playing with the torque management settings I think that may have fixed it. Turns out this car has been tuned previously and someone...

yeah no codes. let me try to pull a log today and see if I can capture anything...are there any PID's I should pull to check for something like that?

so I'm having this rather strange issue...
While tuning my 99 Trans Am with a 4l80e swap and a PCM4Less adapter (love that thing!) but when I get on it the transmission suddenly decides it doesn't...

it's really the same issue thats been discussed - after hot restarts the engine runs very lean for a period of time. i guess what I'm trying to add to this is that it's not just IAT heat soak,...

ok so in everything I have been able to find, there doesn't seem to be a clear answer/solution to the Gen 3 lean hot startup issue. Most have said its IAT heat soak (which it can be for sure) but...

ok so I've set EQ to 1 above 122* and played with the min/default injector pulse table as well as Min fuel mg but can't get this thing to respond to any of this...injector PW still won't go below...

I'm using this 3 bar: https://www.efisource.com/wp/shop/ls1-style-3-bar-map-sensor/

ok I'm gonna start with the OL EQ ratio and see if that helps, if not I'll be changing injector min mg. thanks...

i have some stock 1999 LS1 injectors laying around your welcome to try if you want. They haven't been cleaned or anything but its maybe worth a shot, and you can get good injector data for them.

Ok finally got a fuel pressure gauge on it (been down with the Rona for a bit now) and it was reading ~100psi, which I didn?t think was even possible?so I started looking around and realized I never...

i have cracked the throttle body trying to get it to start, no deal.

so I don' think its a vapor lock issue although honestly that sounded pretty damn plausible to me. what I did was let it get...

Good question, haven't tried that one yet. Will get back to you!

Hi everyone, I am just getting into tuning and HP Tuners, and I'm working on getting my new build tuned and having some issues with it not wanting to start (at all) when it gets hot. I've been...

TTT - anyone?

hi all, I have been lurking around in these forums and the LS1tech PCM forums for quite some time now, and I decided 3 days ago it was time to start fixing my idle problems. So far I have corrected...
