I should have stated more clearly that I thought it was possible to flash the ECU with a FACTORY 3.4 tune.
And yes Bfan, it is mainly down to the larger MAF housing that we then can exploit the added performance of a remap.
The ECU will adapt for a small percentage in increased flow but jumping up to the larger 987 MAF housing it too much without a recalibration. |
Jim - as far as my knowledge goes with Porsche (hmmm almost none!), there is not much you can't do with your DME that the ME can do. If this is what you are thinking of doing. Or that's possibly what your Indy understood I don't know mate
Given your injectors, MAF and O2 are all spot-on and fresh (no codes), I'd simply get a fresh/full tank of that BP Ultimate (or the Tesco's stuff) high octane petrol, and get Andrew or Jon to set you up an appointment on their dyno. The higher octane will be preferred if you don't want pre-ignitions and stuff of the like (pinging). Yes, that's right, you do want your timing advanced a tad mate.
Other than reworking the motor's torque and push a slight increase of fuel injection to accommodate for the increase in torque, there is not much more you are likely to benefit from that casting-manufactured flat motor thingy - unless you get a set of new cams and "much" lighter pistons/rods done (raise the REV limiter to 9k ?!).
The A/F curves for your given air temp/density will also be reworked of course along with getting rid of all UK's emission controls set by the manufacturer, but that's what, 5-10bhp max? What else really.
Talk to the boyz there before.... they know their stuff very (very) well. And you can be on-site and play your own dyno runs (very loud and fun, worth the 2hrs trip)
If you do the timing adv and afford to run the motor on the silly-expansive British 102 RON, then you are in for a laugh mate +30~40bhp minimum. I think the BP's Ultimate (102RON) was 2.5 quids /liter last time I had to drive my cousin's F California from Heathrow to Milton Keynes back and forth. Couldn't believe my wallet (LOL).
