Don Guhl No Longer Tuning Motorcycle ECUs

[mvk24_imp]

Looks like Guhl Motors is no longer flashing motorcycle ECUs. Link to their site and a copy/paste of the notice on the page with particular information bolded.

ECU modifications for any vehicle with a VIN number or registration are not supported. Please do not send any ECUs from any vehicles that have a VIN number, have had a VIN number or any vehicle that is or can be street driven. This includes ALL motorcycles. Any motorcycle ECU sent to us will not be modified and will only be returned at the owner’s expense.

Looks more like legal trouble to me. I haven't been on here much lately but this was sad news to see after not checking in for awhile.

I hope someone else will pick up the torch, especially for those of us that have already had the initial flash and needed updates to the ECU as we modify the bikes.

Your ign map won't need changing if you are playing with airflow.

So if you already have a guhl tune that derestricted the bike, adjusted the ign timing, raised the rev and speed limiter - you are good.

Any fueling changes you want can be done with a power commander.
