thanks (sorry it took me a while to reply), I think I'll probably do that then as the only other benefit I could see of the e38 setup was that ls3 throttle bodies are easier/cheaper to get hold of.

thanks. why? is it actually better at anything than the e38, or just because the e38 isn't that much better it's worth buying a new ecm/harness?

So the situation is, I have a full engine harness/acc pedal/e40 from an ls2 gto, and I?ve got a 58x L76 engine (basically I bought a bunch of stuff at the same time and messed up).

I’m rebuilding...

Hmm no, I'd changed the injector and map settings to be the same as a stock corvette, and the maf is the original l92 one so I'd left that alone. Any tips on where to start?

Would that really...

I've had my swap running for a few weeks now, and I've got an issue where the trans is dropping into neutral - either when pulling away from a stop, or on the downshift when accelerating.

Thinking...

Never mind think I figured it out. It's pin 59 yellow wire "powertrain relay control". Annoyingly I think I removed that pin, so it's trickyer than it should be, but at least I know what I'm doing...

Digging this one up from the past as I have exactly the same problem. Same engine and transmission, and also wired all my pink switched lives to the same relay.

Could anyone help me with the...

So an update on this, and a possible related problem...

I bought an obd gear indicator, and everything seemed ok on that so I'm guessing the scanner was just showing invalid for park while at...

6l80e using a lokar shifter - In vcm scanner my shift status goes: park, reverse, invalid, d6, d5.

"Invalid" seems to work as drive fine (goes up and down through the gears).

Is this normal?

on a 6l80e using a locar shifter, i get prndl status sowing as "invalid" when I'm in drive - it drives and goes through the gears, but i dont actually have a "drive" showing in scanner. it goes Park,...

OK I've got it going! I'd wired the fuel pump backwards, so although I could hear it running I was in reverse.

It's still running a little rough so I'll try setting the map back to something...

actually scratch that - I reset the scanner, added a few more channels for injectors and crank, and now i think i see injectors attempting to fire and map sitting at about 100. could someone check...

ok still no joy - i tried first with just disabling the p1631. didnt change anything.

then tried copying in the ve tables from 05 corvette - still nothing.

I've also ran a couple more ground...

the ve table from an 05 corvette has about half the values that the ecalade does, and he increments are different - not ure how to populate the e38 table from it!?

noob question time: do you mean the main VE tables in the engine>airflow>general tab? I see mine are all empty, but so are the ones from both the original escalade and the '08 corvette file i have -...

thanks! I'll get to it now and report back...

I've got 12v to injectors, plugs, and fuel pump when cranking. wondering if it might be a ground issue,so I'm going to add some ground wires to the heads.

heres my tune:
73790

the only dtc i have its: 0x7E8: P0532 - A/C Refrigerant Pressure Sensor A Circuit Low (Current, History)

heres the scanner log of cranking:
73791

Yeah, and again after messing with the map settings.

I'm putting an L92 with ls3 intake, injectors, and map into a land rover defender - I've deleted vats, copies the injector settings from a corvette tune, disabled starter checks, and changed the map...
