Please explain how this could be an ECU issue? Only issue he had when he bought it was a bad maf (diagnosed and repaired @ EPL). Car was tuned by Tony @ EPL and had been running like a champ. Fuel pump then kicked the bucket. Car ran fine once new fuel pump was installed. Now something else is wrong. ECU doesn’t fit in ANYWHERE here. Plugs? Coil Packs? Could be serveral things, none of which are the ECU. Tony would have really had to eff up the tune for the car to do this…and since EPL is the most renound Bosch Motronic tuning company in North America…I don’t see that happening.
