Hi all

I have been tuning a N/A LS project with a P75 ECU with no problems, now we are going over 210 whp and over 8000 rpm, my problem is that the LS basemap only reads up to 7936 rpms, so I can´t tune over that rpm and my engine reachs 9000 rpm very lean as I get very rich over 8000 rpm, I´m actually using crome and I was thinking to use a vtec ecu and emulate the oil pressure and vtec spool valve so I can control up to 10000 rpm but I´m looking for other options if there are posible with P75 ecu.

I´m from Chile so I can´t contact any tuner nearly

Thanks

 

You can get crome gold, it lets you go to 11000 on nonvtec, or just use that money and get Neptune Demon. It will be cleaner and better then crome

cant you just change the rpm values on the side bar? I know in Hondata you can. LMK how well those rocker arms stay in there for ya
