Check engine light and weird error codes after flashing MHD Stage 2 (93) OTS Map

[mikeag96]

Just got my ECU back from FEMTO and went through all the steps carefully to flash an MHD Stage 2 OTS map (93 Oct.) I'm getting a check engine light along with these codes.. anything to be concerned about?

MODs:
AA catted DP
AWE track exhaust
Visconti flex fuel kit

It seems like the flash was not successful. All those transmission codes normally flag when flashing XHP for example and there's an interruption in the flash process.

I would make sure the car has a stable 12 Volts by either driving the car for atleast 30 minutes before flashing or have a battery charger hooked up, and then flash that OTS map again.

Hopefully that'll flush out all your bugs.

The flash says it was successful. I get the check engine and the codes after waiting 30 sec. and hitting the ignition. They don't come back after clearing it.. I'll try that though.

Yes it can say successful but still not flash properly.

I'm suspicious that you didn't have good battery power before flashing.

How do we know it flashed successfully?

How do I know xHP flashed successfully too?

I got the same codes

My shop says just run it, and for the most part, those codes won't cause any major harm. Enjoy your car!

Interesting.... because I'm on Bootmod3 and I don't get these codes after flashing.

I've only seen it with my MHD friends.

Reflash same map and you should be fine. I had most of those codes the first time, but no battery code. Reflashed it and all was well thankfully

Did you reset all adaptations after the flash?

No. Am I supposed to?

If tried reflashing maybe 4 times now, no difference.

I'm guessing the harness to the transmission from the ECU isn't seated properly.

What should I be looking for to make sure?
