OK... Getting frustrated on my car. I have a 2006 GTO M6 . I have been trying for the life of me to get these injectors scaled to my E40 ecu and the car is just not responding like I think it should. it is pegging my motec lambda gauge on my dyno, af/r gauge in car full rich and the car barely runs . I have tried the Double stoich, halve IVT and inj flow with no luck. I am about ready to put the ls2 stockers back in as I cannot get the ecu to lean out. Possibly I am fighting bad injector data or injectors ( I was sent flow data and printed test results) but even if set the flow table to 63lb max with double stoich it still is way rich. I have tried FIC's 650cc injector data also to no avail. I am about ready to half the MAF just to see i can get something to happen. the cold start and OL is atrocious.
If someone could talk me off the ledge it would be great, perhaps I am missing a cold start multiplier that i need to half as well... I have tuned some ECU's other than GM (dating myself here but Xtronics pocket romulator anyone) so I feel like I have changed the correct values based on my searching in the forums. Now I do have a p0300 and a p0106 setting , although that was also happening prior to the injector swap ( due to the Cam and increase in displacement I suspect )
