Thread: What ECU?

Calum's ECU is on backorder until middle or maybe end of november.

JWT ECU takes too long to receive.

I have SR20VE motor. Can I just use the DE MAF, VE injectors, and DE ECU for my B13 even WITH N1 cams? and also at what base timing?

You'll run very, very rich. Best advice for a temporary solution would be to run the DE MAF, DE injectors, and DE ECU and keep it under 4-5,000 rpm. Or you could do DET MAF, DET injectors and DET ECU and just deal without cam actuation for a while.

This is just thinking off the top of my head though. Any objections?

that's what I was thinking...anyone else?

I was running a DE ECU, n60 MAF, VE injectors with an Apexi SAFC for a while before getting Calum ECU. Car ran great with a little dyno tuning to make sure the air/fuel ratio was not too high

Did you also have SR16VE or N1 cams? I may just go that route, and get an SAFC for now since I may need it anyways with calum.

purchase and install nistune board
calibrate for maf and injectors
retune as required

i ran my old sr20de ecu, with the ve inc injectors, with the DE maf. took out 30% fuel with the safc and ran ok, but not fast.

Found this, hope it helps:

I've wanted to ask this for a while. What is the SAFC for when used with a Calum ECU?

sr20ve stock cams. Should really meter which cams you have though.

SAFC + Calum ECU = fine tuning air/fuel ratio

Yah, but isn't that one of the main points of the Calum? As far as I know you have complete control over fueling. Maybe you don't like burning chips and want to tune on the fly, and don't have a Calum RT? That would make sense...
