Holly hp efi and vaporworx
Anyone successfully run a holly Hp or dominator efi with a vaporworx setup?
Im having issues sbdy can't get car to run.
My dyno tuned global file idles like **** then dies.
A preset but modified global file got it to idle steady snd smooth...but quick ride up hill and 3 point turn and it stalled... then continued to stall after restart.
Now all it'll do is crank no matter what tune i load....72 buick skylark

Is the signal from the MAP sensor being split off into the controller? If so, then I'd say yes, that's part of the problem. Originally Posted by Nothingface5384

As Andrew mentions, yes. Originally Posted by Nothingface5384

Has the ECM been updated to recognize the change in the MAP sensor? If the calibration is set to 1bar, but another sensor is used, the engine will never run right.VaporWorx. We Give You Gas http://www.vaporworx.com

When you change MAP sensors you have to be very careful about the scaling. If you allowed the software to automatically rescale the load axis, that will change your tune, big time. Originally Posted by Nothingface5384

Yep, what Andrew and Carl said. You need to make sure that the MAP sensor is calibrated correctly in Holley, as well as using the correct MAP sensor for your vaporworx module. I'd use the MAP sensor that Carl recommends with his kit, then adjust the tune to reflect that MAP sensor. I ran the LSA 2.5 Bar MAP and Vaporworx together and they worked flawlessly.

I'm on the road so limited response, but there appears to be some sensors that are not attached. Andrew may be able to help.
