Hello all,
I just had a quick question i would like some opinions on.
I have a 26/30 in my Vl calais and it is running twins at 18psi. A haltech 500sprint is the Ecu that is running it all.
Just quickly because i get any responses about talking to my tuner about my issues, I have done this and am in the process of continuing this, however with the new year upon us things are a little slow on the response end and i just wanted to get a few more opinions so i don't feel like a total useless twat when talking about whats going on.
So basically whats happening is that the car is running a bit rich (i was told by my tuner) as the haltech does not have a pre mapped cold start function (told by tuner). Now the car keeps fouling the plugs. I have changed the plugs 3 times in 500kms. Admittedly i dont drive it very often. Initially i was told that my car alarm was draining my battery and the haltech doesnt run well off lower voltage so that was causing things to malfunction. Now that i have a trickle charger in the car the battery is always topped up, but things are still amiss. Also another thing i have trouble with, is that the car stalls under deceleration. When i change gears from 3-2 or 2-1 in town it stalls between gear changes. Unless i keep the revs up.
The car idles at 1250 rpm when warm, however i had to up this a little because it was idling at 400rpm when cold.
My question to the forum is:
Is this all related to the tune? AF ratios and so forth?
or could there be something else im missing???
The engine is pretty much brand new. every bit in and on it are new except the rods which are off the dirty 30.
Thanks in advance
If i have left out any info just tell me what i might need to add to give you gurus a better idea on things.
Cheers
