I was reading through the instruction manual of the Maf Translator GenII and have a few questions.
1. Is it true that the translator only comes into play when the car is warming up or at WOT?
2. I didn't see a maximum MAF limit anywhere, what would it be? Or is there one? If there is no limit then one could make as much hp as possible while still using the MAF?
3. Has anyone besides Harlan used it?
Thanks

My understanding is the PCM can't store an airflow value higher than 512grams/sec for the MAF. Whether or not it will understand a higher "translated" value might be a different question. Either way, the MAF itself will eventually max out - be it limited by it's components or the PCM. If the translator doesn't have any RPM, TP% or ECT inputs, I don't see why it would only come into play at idle, during warmup or WOT unless it's limiting you to the ranges you can adjust. If you can adjust between 3,000~7,000Hz, then you can adjust part throttle. But keep in mind, the PCM doesn't fully trust the MAF unless it has a steady flow above 4,000RPM. Transient throttle or throttle below 4,000RPM uses fueling from both the MAF and VE tables.

You might want to try http://www.fullthrottletech.com/ since it's their product. You'll probably get a faster response.

Is this different than the MAFtranslator I? I used one and observed the grams/sec change in real time at idle with a techII, and found it very useful for tuning idle and WOT A/F ratios.
