I recently bought an 08' GSR and 2 months into having the car had the spark plug detonate. Thankfully after compression and leak tests it showed that the porcelain portion of the plug didn't rip through the engine, or at least it doesn't appear that way. The previous owner had the Vishnu 380HP subzero tune and i plan on getting this removed so i can have my local tuning shop (racing greed in port coquitlam BC) do a custom dyno. I have been on the Vishnu site and there is nothing on sending in the ECU for removal, but Racing Greed tried to access the ECU and it was locked.

Any suggestions on what to do at this point. I plan on calling Vishnu. They never responded to my email.

Any help would be appreciated.

Current Mods:
Vishnu reflash
Swift lowering spring
Thicker Sway Bars
Perrin Turbo Back Exhaust

 

There should be a way to overwrite the lock, Al from Dyno Flash locks them as well and I think you can remove it.

 

On the 10 you usually need to bench flash them if they are "locked"

Totally different then the evo8/9
