Any info on gains with a PPP ecu?

 

215 BHP and 215 lbft to 237 (240) BHP and 258 (261) lbft - MY01 in brackets. There is about 20% more torque in the midrange. On the MY01 you are not getting a full ECU but a sophisticated voltage clamp - I wouldn't buy it personally, but I did buy MY00 PPP.

 

what about on earlier cars MY96?

 

Don't know. But since you don't need to keep a warranty I would choose other methods. I don't think any of the earlier ones surpassed the gains on the later model - if anything one magazine tested a PPP and found it slower. The MY99/00 was much better.

Have you thought about a manual boost controller? Should be as effective and about 80 times cheaper. http://www.dawesdevices.com

 

with the dawes device, would the stock ecu compensate for the extra fueling.

 

Fuelling is MAF based. If the MAF signal is not saturated, the injectors are not at a stupid duty cycle, you are at a sensible point on the compressor map, intake temps, exhaust gas temps and air fuel ratio are fine and there is no knock then I reckon you are fine. In practice this seems to be the case up to fuel cut on a MY99/00 UK spec. Possibly not the case on imports or some other models, but many are using them and the safety data seems OK.
