HI,
I've been having problems starting my car to have it idle right with my E prom (ECMlink) set up. I am able to start the car with my stock computer, but the car idles rough & doesn't rev correctly. Off of my knowledge base. I figure with all my mods I have on my car now, the car needs a ECM to run/idle correctly. I've plugged in my ECMlink & loaded my settings to what it needs to be at from what I've read off of ECMlink Wiki & ECM tuners web site. The car wont start now.


Here is my set up.

-1998 7 bolt 4g6t3
-Rebuilt block w/ JDM Pistons & Rods
-Stock Head & internals
-AEM Fuel Rail
-750 RC Injectors
-255 Walbarol Fuel Pump
-6-AN Steall Braided Fuel Lines
-Fuelab FPR
-Big Greddy Front mount Inter cooler
-2.5inch turbo piping
-Super 20g Turbo
-Manual boost controller
-3inch down pipe & full exhuast (no cat)
-3inch aftermarket turbo intake
-Stock MAF
-Tail BOV
-Magnus Aluminum Air Intake
-BBK 65mm TB
-Koyo Aluminum Radiator w/slim Fans
-ECMlink V2
-Boost Gauge
-Oil Pressure Gauge
-O2 Wide-band Gauge

(I believe I posted every mod. If u think I need to buy/install something else to my set up. Or any adjustments. Please let me now)

I've set my Global fuel to -40% and Deadtime to 330. That was the setting I got off of the ECMlink wiki chart I read. I don't know if there's any other setting I need to input. I'm just having a hard to to start the vehicle with this ECU management.

*** I will post pictures as soon as I can***

Ive just got mine so I am pretty New to it but did you swap yoilur ignition wires over and invert your cas ( cam angle sensor) im not sure on the details on the v2 spec so I am not sure the differences to v2 and v3

And everyone will ask for a log of your car so just post a log of you starting it and they can help you from there

I didn't swap anything over. I didn't know that I had to... What is the reason of swapping the ingniton wire & inverting the CAS?

Also, I'll post a log as soon as I can. I just thought I could post a log when I get it running...
 
Alright, my apologies for the longgggg azz wait. Here are two logs. I think I need to update the firmware on my ecmlink though because when i would try to turn it over, ecmlink on my computer would freeze while i was trying. Hopefully these logs will work though... if not let me know what else you need. Pretty sure the ecmlink on my cars computer is only 2.0 - _ -

You might also need to play with the global and deadtimes in ecmlink. Dave and Tom wrote that chart up as something to just give recommendations, but you would still need to play around to get your exact values since your injector flow rate will most likely be slighty different
 
Ok so the wiring thing was it LOL. Thx a million for the help with that. All the tuning in the world would have fixed my problems -_-.
Now I just have to get it to run and stay on. Wants to turn off after so long of driving it and then coming to a stop
