    EEC-IV tunning myth? Forget!

    You know that myth about EEC-IV tunning? Forget about it!
    EEC-IV is quite easy to tune..just need propper HW.

    This small turbo is targeting for 330BHP with 400cc injectors, T35 bigturbo
    as the MAP sensor is only 2.5 bar....here is the limit.

    What would be your duty cycle?

    No spark cut is a major drawback in terms of protection....

    Good luck with that 90 ...lol

    maybe owner was more optimistic than reality is...at the end, BHP is not important Important is more power then OE injectors..

    currently I stopped on 92% injector duty and 900Kg/h on MAF so this is maximum what OE MAF can calculate...we are not going to do more.

    But generally I can say, every EEC-IV needs CUSTOM tunning!!!! that ECU is nightmare! That old ford MAFs are nightmare too....
    3 used mafs = 3x cheating mafs! car is runnig lean when maf is old!

    done 1,3 -1,4 bar boost...800Kg/h at maf....400cc injectors at 92% duty with bigturbo inside...still on EEC-IV.

    it will need bigger MAF and bigger injectors.
