kevin p Posted September 12, 2023 Report Share Posted September 12, 2023 Hi everyone, I'm having an issue; the engine would not rev pass 2k and it seem like it will not go pass 14.7 map as well. This one has me stump.

Vaughan Posted September 12, 2023 Report Share Posted September 12, 2023 It's not a limit or cut, I would hazard a guess that you aren't putting enough fuel in but you don't have a wideband hooked up so no way to confirm that. Do you have good fuel pressure? You don't have a Fuel Pump Relay Output selected. Quote Link to comment Share on other sites More sharing options...
koracing Posted September 12, 2023 Report Share Posted September 12, 2023 Why are people trying to tune without a wideband? Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 12, 2023 Report Share Posted September 12, 2023 Can you try changing the fuel pump speed control active state to high, and if that doesnt change anything try changing GP Output 1 active state to high. Quote Link to comment Share on other sites More sharing options...
kevin p Posted September 13, 2023 Author Report Share Posted September 13, 2023 Before I've seen this reply, I turned oof the fuel pump control and it works fine. I was planning on changing it to PW control and set up a table for it. I will try screen shot you in your reply tomorrow as well. Will let you know how it works.

I you can't tell an engine is lean when free revving then you shouldn't be tuning. essb00, dx4picco and koracing 2 1 Quote Link to comment Share on other sites More sharing options...

Have been talking to Jose about this just now, set it to open loop pwm control instead of 2 speed relay control. Quote Link to comment Share on other sites More sharing options...

Am I understanding then that you *could* have connected a wideband, but chose not to to prove you're a tuner? I find more information is more useful than less. To each their own.
