PD130 EDC15P MAF-MAP switching question

[Marge]

Nice. Glad it worked (in benefit of planet)

of course

Can you tell me what are the benefits when u use MAP smoke limiter instead of MAF on EDC15? Or is it only necessary when MAF reach measurement limit?

I have just rebuilt a Golf mk4 PD130 and found the MAF is dead so thought I'd educate my self on MAF-MAP switching. Plus I think you could push the max IQ if necessary

What is 1000 ?

If it smokes you are allowing too much fuel to enter before there is enough air to burn it properly. The more you increase MAP based smoke limiter the more smoke you will get. Try lowering it. Or calculate it to 17 afr and it should not smoke.

((EngineCC/4) * (Boost/1000)) / 17

That will give max value to each column in map based smoke limiter.
