Sup EvoM,

Just doing some logging and wondering if some people that know this stuff better than me can check them out (logs are in txt form). My car seems to be running fine to me. The most important things to check is boost, timing, and knock right? What else should i check? Also, the AFRMAP - is that the accurate reading from my wideband, or?

I have a question about timing, if my car knocks and i notice timing pulled about 1-2*, i should be worried right?
ex) 4000-6000 rpm timing would read 9,9,9,10,10,9,12,12 -- does that mean the rpm between the 10 and 12, it pulled 1* or did it pull 2*? just trying to clarify and to understand clearly.

Lastly, what is boost error?

If you need more logs or if i forgot to log something important, LMK!

Thanks
Tony

 

A knock sum of any thing higher than 3 should be not only investigated but tuned out. Your either too low octane, too lean, too much boost or too much timing or all the above.



Did you get a bad tank of gas?

I am pretty novice at this and I hope someone can chime in here. But I have been learning a ton of info and how to tune our cars. here is the link to Merlins guide on how to tune an X. It is the Beginners bible.

also from the manual it states this: "a KNOCKSUM of 3 yields a spark retard of -1.05 degrees"
so for every 3 knock some your computer is pulling 1 degree of timing.


I can try to answer any questions to my knowledge level. But there are far more experienced guys on here.
