Thanks for that info TUF427.

You've comfirmed what I've been told about EEC-IV's. They were much more flexible than the latter EEC-V's,from AU1 to AU3 Fords.

I made an assumption that Pete's NC Fairlane was EEC-V as the news isn't as good. The EEC-V is programable, just hard to find someone who knows what they are doing. I have done mods to my AUIII (EEC-V) Tickford motor (came from a T3) and not surprisingly I lost power as a result and fuel economy went out the window as it needed to be tuned which was all part of the plan. Took it to a very reputible and nationally known Ford aftermarket specialist to reflash it and the most they could get out of it was 180rwkw up from a baseline of 160rwkw. From the factory these motors made about 190rwkws. There was bugger all torque.

Rather than continuing to pay idiots to play around on the dyno as I later found out that all they were doing was using CAPA generic tunes instead of actually tuning the car, I bit the bullet and now I'm using Autronic SM4 and have got 230rwkws at 5500rpm (the maximum it was reved on the dyno as it happily pulls to 6300rpm) and 560nms of torque, up from 500nm from the factory.

The plan was to build a very streetable 400 odd hp motor, up from 340 horses from the factory. In the end I got there. All I need now is more power!!!!!

Fuel ecomony is where it should be and keeps improving as I trim up the crusing areas in the mapping.

Everyone else who I know from our club who has modded their EEC-V engines have had to use aftermarket computers after first trying not too.

Anyway I hope this info hasn't confused Pete too much. I'd just suggest, whether EEC-IV or V, you ask lots of questions first.

Cheers
