Im about to get my car tuned but am getting some conflicting advice (as always)I do notice however that most of the guys putting down decent power on the forum are using the capa unit.Thanks for your advice,JT Link to comment Share on other sites More sharing options...

Unless you have a car that doesn't cause issues with replacing the PCM, it will be of little benefit for you to. The ford PCM controls not only the engine but all other electronic sensors, safety devices, transmission, etc and the Haltech cannot. Piggy back devices have more or less been proven to be a waste of time and money, when you can get the stock PCM "reflashed" using the capa edit. Since the PCM does EVERYTHING that you require, it makes sense to use this to your advantage. Link to comment Share on other sites More sharing options...

M800? Im curious to know why it did not perform very well? I wouldnt use anything other than a CAPA flash tuner on my car for a number of reason one being cost and it functionality but would be interesting to see what your experience was with the Motec.Also do Haltec have ab ECU that controls the dual VCT?Cheers,←I used the Motec M800 initially, as my project began well before Edit hit the market.Motec was good at the making the power, independent cam control, and driving big injectors. However, the major issue was idle control (with a lot of idle "hunting"). With an aggressive triple plate clutch the car was undrivable, as I basically stalled the car most of the time. Cold starts were not very good.With the Edit the car starts and idles well, independent cam control is available, the tuning is far easier, with far more control over the car's tuning parameters. It can also drive big injectors (with a workaround).Brian Link to comment Share on other sites More sharing options...

It is a fantastic computer, but as my 1978 Falcon didnt leave the factory with a ECU or fuel injection, we had no choice! Link to comment Share on other sites More sharing options...

Awesome value for money... but the current technology in cars these days controls more than any aftermarket ECU can control, and this has to be the best way. The down side of course is the lack of live tuning, increasing dyno time/tuner time and some "hit and miss" strategies. It's down to a fine art now though and often a car is properly tuned after one or two attempts. Link to comment Share on other sites More sharing options...
