Thread: tunning my 2g..

i don't have all my log numbers... but at the top of 3rd 7000 rpm my o2 read .98v, timing 16* @ 17psi. My question is how am i going to get my timing to go up higher..? it seems a little low..

.98V /w low timing usually (usually) means your running rich, just based on a pocketlogger reading. I would lean it out to about .93-.94V and see where your timing is at again. Or just buy DSMLink and put the timing where you want lol.

Thanks...

Also, what are you using to tune and what turbo do you have? 16* is just about all you'll get from the 2G ecu, assuming you're on the max-airflow curve.

16* MAXX that it... that sucks... I am running an 18g..

Well, you answered half the question anyway. I would guess that an 18g at 17psi would give you enough airflow for 16* to be about normal. If you can log airflow, we would know for sure. I think 17* is normal at the rpm point you specified, maybe coolant temps or knock pulled a degree.

Whether or not 16* sucks is an entirely different discussion.

Do you have an SAFC wang?

yup... got one of those too...

I wasn't so sure about 7K at the top of third though.

Stock fuel delivery and intercooler?

Fuel corrections with an SAFC usually leads to higher than normal timing, so I'm going to guess you either have a stock fuel system and the SAFC settings close to zero, or you have larger injectors and a lot of knock. Either way, I wouldn't try to get a whole lot more timing; I'd try to concentrate on being able to run more boost.
