Generic tuning ?'s from a first timer
Hello,
I just recently finished getting my turbo kit installed and am finally to the tuning part of it. I have played around with the S300 for a couple of days and have a few questions.
1. Cold start fuel correction: I know that cars take more fuel on cold start up. But, is the extra fuel to keep an A/F ratio of 14.7 or is it supposed to run rich until it warms up? My car seems to run right at 11.5-11.7 and works its way up to 15.0 as it warms up.
2. Tuning the ignition map: Is it best to keep 0* of knock retard? The car seems to run fine and I don't hear any pinging (although with the open dump I am not sure that I could hear it if it happened). Looking at the datalogs it seems to pull about 4 degrees of timing while in boost. I guess I could take away a degree at a time in those parts of the map until it has no more knock sensor interference? I do have the boost table set to retard 1* per pound of boost.
That's all I can think of now, but will post more questions as the come up.
TIA,
David

Re: Generic tuning ?'s from a first timer
Depending on your fuel injectors there is a gsr with 550cc injectors and a sc61 turbo tune in the s300 calibrations. Another thing is I heard the factory knock sensors on the b series motor will give false knock and cause the timing to start retarding. There is a good DIY device that you can make and it'll let you hear if your motor has knock or not.

As for the knock tool, do you have a link to the DIY? Thanks for your input!

Re: Generic tuning ?'s from a first timer
I kinda figured that would be the case. I plan on running the wastegate back into the exhaust because with a 3lb spring it is open almost anytime I am on the gas. I have a couple extra sets of plugs and was planning on pulling them out Saturday to take a look. I have never read plugs so I will have to find a good article on it. Is there much tuning required in individual cells of the map or is it ok to just highlight the entire thing and use the "-" button to pull timing everywhere? Thanks again!
