Hi guys.
I used Enthalpy's instructions and generate a timming map for my S14,
SR20DET - with Haltech E11V2.
Thanks for that man !

SAVE AS, for EXCEL :
http://www.max-tuning.com/gallery/mypics/mytiming.xls (http://www.max-tuning.com/gallery/mypics/mytiming.xls)
I am currently runing about 18-18.5 psi, with 11.3-11.8 AFR's.
My EGT goes up to 1540F at to of Fourth, at about 124-142 MPH.
I am using 98RON fuel (thats what we have here) - wich i belive is more like you'rs 93RON actualy.
I allso have the www.Phormula.co.uk (http://www.phormula.co.uk/) Knock analyser pro, rigged in to my sound system, to hear for knock - though i admint iam not sure what it sounds like, since i never heard any....i still dont hear any knock.
Car was tested rolling at 62mph - 124mph in 8 seconds (meassured with Greddy E01).
Havent had a chance to get to a dyno yet - this will have to wait a bit.
I was wondering a few things....
1 - What do you think about the timming at 18 PSI and up, vs Top end RPM ???
am i too conservative, or do i have a bit more to go ?
Its 19.2 DEG at 18.5 psi...
2 - I know that as RPM goes up, because of the leeser time for the mixture to burn, timming needs to be advanced so the mixture gets burned before 15-20 ATDC...
Why is most of the High load, High RPM range above 3500 - level off to the same value.
Meaby Enthalpy can give an insight to this ???
3. Any other Tips, would be greatly appritiated, as i am doing this for my first time, and am eager to learn...
Thanks,
Dany.
