On second thoughts... could probably have simplified that from 2 NPN and 1 PNP transistor to just 1NPN & 1PNP... oh well.... should be an interesting weekend.

Heres the circuit diagram for the switcing procedure http://img855.imageshack.us/img855/1144/dualromv2switch.jpg + T1 enables C1 by default by applying '1' to the base of T2. + When you ground the base of T1 with the base of T2 via its 4.7K resistor, you enable T3, disabling C1 & enabling C2. + ...

Okay after last nights dismal demonstration with the dual roms, I decided to re-think the whole thing over and start from square 1 with the design. The problem with the stall was with the actual 'switching' process itself. The switches 'toggle' time is somewhere in the 'miliseconds'. The ECU clocks ...

Tested it on the ecu, heres the results:
+ Switching on the fly while the engine is running = stall
+ Switching before you turn on ignition = works

Cheers.

Hey guys, Lately I have been curious to know if it was indeed possible to run 2 rom chips in the ecu and toggle between both on-the-fly. So today I put some time aside to give it a go. I havent tested it in the ECU yet, but works fine when toggling both chips on my programmer [Will do an ecu test so...

Yeah I was looking for a premade bin image with improved shifts and points. (its an auto)

Cheers.

Hey guys,

I was wondering if someone has a spare performance memcal image which they wouldnt mind sharing with me. Its for a stock VS V6 station wagon. Any help would be greatly appreciated.

Thanks in advance
Cheers.
