eCtune

I was tuning a car this weekend with one of those \"other\" systems (not eCtune) and came across a realyl odd issues when tuning WOT. For whatever reason, when the owner went to 100% tps the car just shut off. Wideband went lean, car just stopped. It was super violent, just like the injectors and ig...

Your ecu will function fine without that. Im not 100% sure what it is, but I have chipped many ecu's with and without it and they all ran fine.

Your missing both capacitors, resistor, and logic chip.

Your missing like half the chip kit there. Here is what it should look like.

Have you ran this ecu chipped before? I kind of feel like this ecu was chipped and had problems, so J1 was cut and the ecu sold.

It shoudl all be fixed once your running eCtune.

When an ecu is chipped, it is assumed that the jumper is installed. By not having the jumper, you are are running off the factory settings so technically, you are not chipped.

Haha, beat me to it!

Theres your problem, simple enough. Just add the jumper back in and enjoy eCtune.

Im confused here, so the car runs normal but eCtune is not connecting?

That is correct. Is the ecu a known good one?

Haha thats really cool. Nice job!

Same issue here, if you update the first time, save and then click no to update next time you open it will still work fine until Calvin gets it all straightened out.
