Sooooo, Are we going to see a for sale thread on the Clone ECU or the Arc 2? ;)
Currently trying out an Evo MAF to see if I max out its flow. Probably going to end up selling the ARC 2. Maybe I'll bring it to the NG with a 25 spline mark Williams 5 speed output shaft and some other goodies for quick liquidation.
ill take the clone u can keep the arc ;)
Set the ARC to stock injector settings. Double the MAF size value. Fine tune using the MAF comp (VE) tables.
Well . . . Here is how it turned out. I went with a stock Evo MAF and removed the ARC 2. The horsepower came in just under what the piggy-back tune had but with lots more torque.Attachment 6878
Here is the dyno results from last year at the STL NG. ARC 2 and stock '93 ECU.
Dat torque curve!
The only reason we stopped making power is the size of the Evo MAF. You can see it in the HP curve, the line for the 83mm ford MAF keeps climbing to the rev limit. The Evo MAF shows it's restriction by limiting the boost at higher rpms.
The big question now is deciding to go with 2 Evo MAF's or a z06 MAF and translator.
I've been thinking about using 2 MAF's too. I know that the old skylines use 2 MAF's in their stock configuration.
