Connecting Wideband via AC Pressure Switch for HPT
 

I've had a thread about this before but didn't get the answers I needed. There use to be a how-to supposedly but it has disappeared. I have the Innocate LC-1 and HPT standard. I just need the steps to finding the ac pressure switch and what to do. I have the info about pulling it up in HPT.

Checking interwebs.......... http://www.ls1tech.com/forums/pcm-di...thout-eio.html might help until I can find the one that is here.

This one's not too bad:

Ya. I've read that Corvette one. But what I don't understand. Do I tap a wire into the ac pressure switch from the wideband to the switch? And what wideband wire do I tap in to?

From what I understand you are putting the signal wire from the wideband into the AC pressure signal line. Then in HPT you are using the signal coming from AC pressure as your wideband signal instead. So for it to work, you can't have the AC on while logging. If you add a switch you can make sure you can turn off the wideband after logging so your AC pressure is sensed correctly. That's my take on it - haven't done it yet........HPT coming with my TVS, but still making payments............

sub'd because i need to find out how to do this too

Don't be cheap. Buy hpt pro. Your ac system is gonna overpressureize and blow out. Don't ask how I know.

Haha. Hey guys, I'd listen to Kenny - I think he said in another thread he did the origina how to that is now missing (probably due to HPT being a vendor and not liking it - a guess).

I have everything hooked up. But I can only get it to read in volts

That Corvette forum had some info on how to config HPT.....
