Well as of this past weekend , I now have the wiring done and looking better. My. 2 bar map came in last week so I installed it Friday night and the car starts great . So nothing else at this time . John is coming back out for some tuning soon . Will update you then

Update:

We tuned Roberts car today. Went very well. With only changing the injector constant the car was pletny drivable on just the GM reflash. In fact it was super RICH!!! VE offset still at the 20% that the Reflash comes with. We just took fuel away. Still have a littlemore to take out, but might just make that up with more boost. We were seeing 15.-16 psi all day, and she runs great!!!!!!

This 100% works.

Hopefully some video's and dyno numbers in the near future.

So, kind of a stupid question BUT could this be done with a swap harness and no sensor changes. By a swap harness I mean de-soldering the connector out of a junkyard eco pcm, then using 6-12 inches of the ld9/ln2 main harness and just going from the eco pins to the ld9/ln2 pins. This would make it easy to switch between the 2 pcm's come state plug in inspection time and also not require rewiring most of the engine bay. Is there any reason this wouldnt work?

I'm sure it might be possible. Problem I see is things are different between the LN2/LD9 and Eco harness and ECU's. You can't run a Eco coil housing on this setup. Using a LD9 or LN2 harness and wiring a few clips is going to be much easier.

For state inspections I would think the VIN not matching in the ECU is not a big deal. What happens if your ECU took a crap and you got one from the junkyard? Ecotec swapped cars would not match either.

I do not live in a state with these type of inspections so I am not going to try and act like I know for sure, I do not. Just my thoughts.

So......we need a ecu and harness out of a 2k up 2200?

or ld9 will work too i found one local at a yard for 50 bucks for the harness and the pcm ill see if they have any more and if they do ill see bout pulling them and selling them to ppl that want them on here

Cavy2nv 314hp 324tq dyno day

This vid is of the 5th pull and only shows the 310hp pull (in red ) We made two more pulls and got 314hp I will upload the chart when im able to scan it sunday

any new updates to this mostly how effective this would be on an m62 setup? Also I already have msd dis2 and coils so would anything really need to be changed there aside from rewiring the dis2 and tossing out the ecotec ICM/msd camsync?

Car runs fine on this. It would work the same on a M62 set.

I think I would really recommend getting a LD9 engine harness over a LN2.

I guess you would need to drill and tap for a threaded IAT sensor and also use a 2bar map vs the 2.5

No just rescale everything to 2.5 bar in your head. Or just start tuning like normal but with a 2.5 bar sensor, the computer will never know the difference and if you dont think about it too hard the tune will come out the same. Do consider dropping the pe enable map like 5-10 kpa.

So you think just wiring the tmap into the LD9 harness just like it is on the L61 harness would work? I am unsure if I would go this route likely will just get a new ecu and fake the 2.5 but I am curious about this not like the car is a daily driver so I may get bored later in the year.

Yes exactly.

I agree with Leafy also.

Hmmm might be worth a try



Re: Eco on LD9 SC Reflash

Im not sure this has been asked and if it has I apologize. Is it not possable to just run a 2200 pcm on the eco harness then? The PCM's are identical from what i can tell did GM just pin a few thing differently between the two?



Re: Eco on LD9 SC Reflash
Saturday, February 19, 2011 4:12 AM
SS-J - the pcm's are not the same. The 2000 and 2001 2200 pcm will take the LD9 s/c reflash, and obviously so will the 2000-2002 LD9 PCM. The 2002 pcm is the same as the eco, but different from the others above and you will get a vin/os mismatch. Last year I was highly excited to find the 2002 2200 pcm was the same as the eco hoping it would take the flash, but it's basically like a different platform of pcm.
