Twin engine GTP project progress thread

[TwinV6GTP]

Problem could be same as I had. The RPM signal is more of a sawblade wave and usually the external electronics are looking for a square wave.

Possibly a MSD 8913 tach driver box or the sorts to convert it to the square wave.

It could be but what is strange is that the signal looks good at times (stable) then will starting showing double more RPM or lower rpm erratically. Looks more like a dirty signal more than a signal type issue.
My AEM reads it to perfection. Normally the AEM can't read the RPM right on most other machines I had it on (Side by side and snowmobiles)

My HKS boost contoller reads RPM perfectly it seems. But the Aeromotive speed controller had issues. Even with a deal PRJ built to clean up square the signal, it would still switch to highspeed and back to low at idle every 30/40 seconds.

Removed it all together, and idles perfectly. So now just using a hobbs switch to toggle highspeed on the controller once boost hits.

I tried to do any little tricks, new twisted pair wires, ect to try and get it a clean signal.. and nothing would work like desired.

Figure its just the clunky device it self having the issue.
