[Galant VR4 Setting up input for launch control]

The DI's can be switched to ground or to positive, they can be set up to work either way.  So you should be able to just connect it up to the stock wiring and it will work.

Sweet thanks, probably just a bad switch then.

Put one side of the switch on a chassis ground and the other side on your DI pin

If I do this but leave the original ground for the switch untouched, shouldn't it technically be grounded through the stock harness already? Since there's a power and ground going to the switch from the factory.

[Galant VR4 Setting up input for launch control]

Hello, I am having an issue with the input for launch control. I am using the plug & play galant vr4 ecu in a 92 plymouth laser. I believe my clutch switch is bad so I'm in the process of hunting one down to install but I'm not sure on how to wire it to the ecu.  I see digital input #6 on the expansion loom is not used but do I wire the positive or the ground on the switch to the input? 

Ive tried setting up launch control based on mph using Digital input #3 (speed reference on the ecu) but for some reason it still arms the system at 20mph+ versus disarming after 10mph.

Thank you

Tried messing with settings and it continued to prevent me from revving farther than 5k. Ended up turning launch control completely off and the car revved out. I was not prepared for that and was caught by surprise LOL. Now I just need to get a good calibration table for my wideband to read correctly on the ecu.

So you think the car is trying to hit launch control mid pull? Ill double check my settings and see what I need to change.

[Integrated MAP sensor not reading properly?]

I was wondering if anyone has had an issue with the integrated 4 bar MAP sensors? Using the plug and play Galant VR4 ecu. The MAP calibration says that its successful and working but when the car is running at idle it reads around 8-10 psi on the ecu vs 14-16 inHg on the boost gauge. Then when I try to do a pull in 3rd, it will read 38psi+ when the car is only making around 20 psi on the boost gauge.

I think this is what is causing me to hit a fuel cut at 5k rpm because the boost table is setup for fuel cut. Wastegate duty cycle is set to 0% as well. At this point I'm not sure what else is causing me this issue.

The pull starts in the 19 minute and 20 second range on the log file.

Thank you
