difficult to start after recent upgrade flash

Postby mksevo » Sat Feb 03, 2007 5:21 pm


I just did the latest silver box flash to get rid fo the P0300 code and that worked but now when i start the car it studders and dies usually. it will restart ok on the second start whats up. anyone else have this issue. i did have my idle at +3 on the fuel due to my cams . i put this back to 0 and still no help. idle smooth box set at 4.

thanks Mike

Mike -

I haven't had any reports like that. Send me an e-mail (support@ecuplus.com) and we'll see what we can figure out. The new firmware should be universally better at starting the car.

I've had no problems.

I coincidentally did have another P0300, but I also got a "system too lean" and I think that's cuz just at tip in (~100 load) I have my map set to something like 16.9:1 to give better response. I don't think the car likes that. I think this was a fluke P0300.
