yea and not for the better, except at high throttle settings.
It started, idled, and cruised better on the chipped/maf setup, was cleaner in aircare, and got better mileage.
That said, my car was very well dialed in on the MAF. Jeff O and I did a few revisions and I played around with a few things. Jackal may make a poor or average car run better.
The thing about Jackal is that you have to tune EVERYTHING. Not just timing and fuel, but the iat curve, the coolant temp curve, and other things you would take for granted on other tuning systems. you have to input your own injector dead times for all the voltages from way low to way high. you have to enter your open loop/closed loop tps settings etc. And one mistake in one of these tables will mess it up. Its hard to know where the mistake is. The car will run "fine" but it will be off. And the tune can change day to day making it hard to pinpoint what you are doing.
Plus as it stands, there is no actual intake air temp sensor. It should be called a charge air temp sensor as its in an intercooler pipe and it heat soaks when idling in a hot engine bay.
