Hesco 274 Cam

[MrShoeBoy]

The PCM has been unplugged for over a month so I doubt theres anything saved. The motor didnt like to stay running, as the cam does not pull a lot of vacume at idle. Once on the throttle under load, it seemed to run better but theres still some hesitation and surging. I still have to tweak with the Apexi to see if the stock ECU can manage. This was with all "factory" settings, I took 5% of fuel out at idle through 2000rpm with the Apexi and it worked enough to get me around the block. I think it needs more fuel taken out. The lack of vacume from the cam is making the computer thing its running higher RPM so theres a lot of fuel being dumped in. Once I get the wideband I will be able to see how well it can be tweaked before the MS goes in.

Bump this thread up. I have the same cam and I'm having the exact same issues. Did you ever get this running correct and did it ever make any vacuum?

Thanks
