General 1g with 2g ecu swap, wont run right at all.

[onefast2gdsm]

Ill start at the beginning. I bought this 1g from a friend who had it running fine. He sold it to me without an ecu, turbo, battery, exhaust. I wired in a 2g blackbox, put on my holset hx35, bosch 1600cc injectors, 300lph pump, afpr, 272 regrinds, wired in speed density, put my lc1 wideband as the primary o2 sensor, and removed cruise control and a few other things.

I flashed ceddy mods with speed density to the ecu, setup my injectors and tried starting it. It started for a few seconds then died. I had a buddy come over who knows more about 1gs than I do (im a 2g guy) and we got the car running but it was running 10:1 afr and we couldnt get it to lean out. We also switched to 720cc injectors with no change in afr. We came to the conclusion the spark plugs were fouled and i had a huge intake gasket leak.

Over the next few days I replaced the spark plugs with br8es and changed the intake gasket switched back to the 1600 injectors, and did another boost leak test. I had another big leak going to my boost gauge, so I also fixed that. I started the car, it was idling around 2000rpm, leaner than it was before (around 11-13:1 and then after a minute or so it would idle down to 1000rpm and go full lean (22:1) and then die. I got a dsmlink ecu to use for diag purposes from a buddy since that is what im used to tuning with and the car runs exactly the same. I switched back to the 720cc injectors, with no change as well.

It seems when the car is trying to go into closed loop thats when it goes full lean. Ive tried different injector settings, messing with the VE table, checking my fuel pressure, etc. and I cannot figure it out. I have good compression on all 4 cylinders, getting spark and fuel on all 4 as well. I alsodont know why its idling so high. Messing with the biss screw doesnt affect it and neither does adjusting the cas.

My guesses as to what may be causing it is: 1. its running open o2 housing so the o2 sensor is close to the end of the exhaust. I was told by a few people that shouldnt matter. 2. i have the wrong injector settings (i tried two different size injectors though) 3. something is wired wrong (i can flash the ecu and datalog it with evoscan everything seems to work)

any help would be appriciated, Im going crazy trying to figure out what is wrong with this car!

Does it keep going lean and dieing even after the motor has warmed up?

Yes

Car still isnt running right. I fixed 2 injector plugs and it helped a lot. I verified mechanical timing, swapped coil packs necaise of coil pack cel, swapped to a maf, and its still running rich then leaning out. I tried locking it in open loop and it ran for awhile then died.
