IT RUNS!

Well it has been rough going, but I can say that most of the glitches and BS have been caused by bad ground connections and ghost values left over from the config file I used from Marcell's 4 cylinder turbo motor.

The problem with the USB/serial adaptor crashing when the engine starts was caused by a loose ground on one of the coil arrays. It was hidden behind another wire so I didn't notice it. Let that be a lesson to me.

The engine would start but not run at all until I zeroed out all of the values other than what I knew applied directly to my engine. The early advice was to use a working config regardless of the motor it came from but that proved to be more work that if I had started from scratch. The VE map that megatune created seems to have been ok and VE learning has re-written the spark map after just a few minutes of playing the throttle at operating temp.

See the links below for the VE and spark maps. There has been some good info from the various VEMS brothers that I'll try to preserve along the way, although this page is going to get way too long and confusing so I'll be editing.

USE THIS INFO AT YOUR OWN RISK, I AM NOT SMART

Being that my own project was about to join yours in the Pacific, I loaded your config into my board so I could read it, here is what I think, KEEP IN MIND, MINE IS WORKING, JUST DIES FOR A SPLIT SECOND

BASIC SETTINGS

CONSTANTS

PRIMARY TRIGGER

FUEL PUMP


Fill in these pages with all the required info and watch your config be pretty much built for you
