ZX2 Tuning Decision
Hello, I have been building a speeduino for my 1999 zx2, but I just discovered the definition file on this website to use quarterhorse. So now I am thinking of tuning the factory ecu instead of going through the hassle of a speeduino. I am already pretty invested in the the speeduino but I'm not set on using it. If someone could chime in on which path I should go down, it would be appreciated. Right not the car is stock but at some point down the like it will be getting a small turbo.

Re: ZX2 Tuning Decision
Should the strategy file that's posted work straight out of the box, or will it have to be personalized?

Re: ZX2 Tuning Decision
I believe KRAF5 does not cover the ZX2 box codes, especially since the focus never had VCT except on the SVT which used the black oak instead of the EEC-V. I will eventually be pulling the trigger on premium membership and installing the QH on mine. The 3v in my truck might need to be replaced, but with time and money being short it's been really delaying everything.
hijacking the thread a bit here... decipha, have you done any lean burn tunes, or tunes for fuel economy in general? I imagine this is as more or less as simple as setting target AFs in the lean range and running open loop. This may be the direction I want to go on my ZX2 for now.

Not gonna happen on a zetec. They are very fuel specific engines and if not in their sweet spot will run like absolute garbage.
