Mail order tune. S14 super charged VN V6 Gemini
Posted: Sat Dec 26, 2020 3:47 pm
Hi everyone,
A little bit of my background, I'm very hands on at building cars and getting my hands dirty. I'm old school carby with a "do it myself" farmer attitude.
However....
I built a 79 Gemini in my early 20's running series's one VN V6 with a S14 supercharger.
I had it tuned with a E6GM Haltech ecu.
It was tuned to "work" at the time but I have since learnt that it's a very poor tune and it won't even idol when cold.
I put the call out for some help with it, when an old friend responded with a modified Delco unit, using tunerpro RT to make changes to the tuning.
The friend was able to source a bin file final tune from another VN V6 with S14.
I've been able to load the bin and run the car and drive. It does feel much better and is now controlling the TCC. We've been able to calibrate the speed sensor pulses and set some of the options to suit the application.
I am running a tech edge wide band with good feedback.
When I say "we", I really meant my friend has been able to do this remotely from his computer and location.
Although very computer literate, he's not confident to adjust the tuning and is very time poor like all of us.
According to the logs, the desired AF ration needs to be richer under boost but also needs to be leaner on idol and cold starts. The IAC doesn't appear to be opening enough for start up and requires me to press the throttle to start it and run for a couple minutes. Although, leaning it out a bit may help with this.
I have 3 logs of recent drives and a cold start log.
I'm so far out of my league to even know where to begin to bring the tune to the desired level seen on the replayed logs.
Is there's someone who is willing to make these changes to the bin, then allow me to do some more logs and repeat a few times until we arr following to the set points on the acquired bin file?
Happy to pay for the time required to achieve the end result.
Thanks
Kingsley
