Recently fired up my S1 R25DE+T, engine has received alot of work over the last 6 months including larger turbo, injectors, fresh gaskets throughout etc..
First time starting with new setup and eprom tune.
Runs pretty good, still have a few little things to sort but its all there.
The engine now runs 550cc RX-7 injectors with walbro 255 LPH pump and adj pressure reg.
Its sometimes hesitant to start, I believe its putting too much fuel into the engine whilst cranking, I deleted the cold start valve when I did the new setup but am now thinking of putting in back in, I have done a resistance test on it and its perfect according to my R32 workshop manual, will this aid in supplying less fuel to the engine on start up? Or put the engine in open loop and put even more fuel in? basically, Will this help the engine start?
Any info/help is great as start up is really the only issue, it currently has no O2 sensor but I will be putting a new NTK item in over the next few weeks with new downpipe, vehicle has only idled/lightly revved so far.
Cheers
