I know this post is also in the Wanted to Buy section. Bear with me as the issue is both tech and Marketplace... you shall see why

Recently had my car tuned at PSI in Hillsborro
They wired in Apexi DJETRO Correctly and Intake temp sensor to S15 harness correctly... new aeromotive 400 pump 750 cc injectors and a T3 turbo, mapped for a Q45 TB using Map Sensor

Car made Decent Power 340-350WHP on mild boost

Great News !

Not so Great News:

The car started to have issues right away after getting it home
kept losing signal to coil packs and injectors.
now we have a no start from the ecu (cas,iacv all good)
running djetro. Borrowed a power fc djetro from a friends s15 with a map by the same dyno shop (luckily) and car starts... still only getting signal to two cylinders... stumped here.. think it may be in the wiring ? We already rewired coil pack subharness as stock harness was brittle , added better coil grounds for each coil. Still no start condition, fuses and relays are all working and in good condition

Any sugestions here guys ?

I have attached pics of the grounds,the tps wiring,ecu and ecu board, and a few others that may or may not be helpful here...

My Power FC is the Blue one the other one is the donor

Here is the Board from my PFC

Q45 TB Wiring Pic

New Coil Pack Grounds

Grounded to Firewall

New Power ran to Coils

A few pics of how she is sitting.. so much potential here guys ! Help

Posible replacement stand alone needed while i send mine to apexi japan for diag/rebuild.. We are in the middle of drift season and id like to see this thing run, I am missing all of the smokin times....

I have heard there are a few companies in the us that can fix the power fc ECUs. Mine may have fried...

thank you
