Mk2 Hard limiter no longer functioning

Post by Kyle_TSI5 »

I’m in need of some help. I am running the MK2 unit, and overall am having great results. Up until yesterday when I had realized my limiter is no longer working, where it has previously in the past. (Loud bangs and pops, no more rev’ing) Currently, it hits the soft limiter, goes to 0 degrees advance, then continues to rev past the hard limiter. No matter what rpm it is set at. Same result with ignition map 1 and 2. I’m fully aware of the committing to flash feature and what not, so I don’t think I’m stepping on my toes there. More info, the limiter shows correctly on screen, rpm and commanded timing are correct, and the wiring is correct with appropriate gauge. Everything was working perfectly up until yesterday. Have there been cases of bad units? Software glitches? I’ve tried writing a new map from stock, with no luck either.

Any tips/tricks/advice would be much appreciated
