P0244 CEL Reasons

Ok, I didn't really get around to flashing the changes to my ecu rom as mentioned in my previous post. The main reason is that the P0244 CEL is an indication of me not doing things right.

Firstly, my boost limits are set at 1.4 bar and I am boosting at 1.7 bar, that's why I am getting P0244. See screenshot below:


But setting the boost limits higher is not right because I'm running my OL MAF Scaling with my methanol injection. This is not right:

1. my MAF Scaling is not accurate (methanol skews the MAF scaling)
2. MAF scaling should be done on fuel pump only so that in the event of my methanol failing, I know that my engine still runs fine.
3. Also, I should not be boosting at such a high boost when MAF scaling when my car has not been tuned for it. 1.7 bar is pretty high and in the logs, my Feedback Knock Correction* (degrees) when to -4.22 degree.

Actually 1.7 bar is pretty high.. my engine could blow if my parameters are set correctly. :-(

For those who wants to see what others had to say about what I have been doing, here's the thread on romraider: topic3279.html


I've emailed Rene and he's been helping me abit. I'll update it on my next blog post.
