So I just had my Power FC installed and I was told not to ever jump start the car now that I have it. Something about erasing the map and/or ruining the computer. Is this true?

I ask because I have a wiring issue with my turbo timer and sometimes when the timer goes off the fans won't and it drains my battery. I've be trying to find the problem, but with little success, but since its only happens 3-4 times a year I haven't been worring about it to much.

Thanks for anyones two cents

I have jumped my car many times before when I had my PFC. If your that worried about it save the map file with a datalogit so you can always upload it again.

I think whoever told you this is smoking a little too much weird stuff.

There is some truth to what you've heard. You need to be careful with any car when using the start boost function of most of the smaller battery chargers. The starter can pull a huge amount of amperage and if it's pulling more than the battery charger can shove through it's inverter it's possible for the inverter to give in and allow 110V AC through to the car. In this case the ECU can be damaged. Though I've never had it happen personally (I use a commercial type charger rated to 200 amps) I have heard from others of ECUs being damaged.

Jumping from another running car or something like a boost box should be entirely OK.

I think he actually ment pushing the car and poping the clutch in first to go vroom vroom.

Ok. The electrical engineer who is head of product development for the leading seller of aftermarket engine management systems who told me this must not know his *** from a hole in the ground. Sorry for wasting you time.

This is kinda unrelated, but I am a Kohler engine dealer and we had some problems with frying computers on the fuel injected engines. This would happen when the customer would jump start the engine. It was fine as long as the cables were still attached, but when you unhooked the cables the current draw would spike and fry the injector circuit. Kohler now recommends not to jump start but if you do, leave the jumper cables connected until the engine is turned off. Kohler uses a modified Bosch unit from a Fiat.

That is the problem right there. "Made for a FIAT!"
