My name is Paulo, I'm from Portugal and a proud owner of an E30 with an S38B38 swap.
This will be my first standalone instalation and I think of it like a learning experience, which will require all the help I can get.
Some information about the S38:
OEM ECU: Motronic 3.3 - 88 pin
COP with igniters in the OEM ECU (not sure)
60-2 CKP
Single Trigger CMP (not sure)
Ressonance Flap in Intake Manifold that works with air pressure(changes effective runner lenght with 2 rpm/tps changeover points)
Stepper ICV (not sure)
Engine is stock
Objectives:
MAF delete
Learn as much as possible about EFI and its instalation
Tune it myself
Prepare for further mods down the road (turbo mayhem)
First set of questions:
1 - AFAIK this engine sports sequential spark and ignition from factory, should I try to keep that up with MS3 or would that be to hard for a novice user?
2 - Can I control the Ressonance Flap with some sort of PWM or on/off trigger? Maybe with a boost solenoid?
3 - Should I use the stock wiring as far as possible or ditch and do it all myself?
Thanks,
![Yeah! :yeah!:](./images/smilies/icon_yay.gif)

PS. I'm buying a pre assembled unit cause I am not nearly smart enough to build my own
