Ok so I picked up a used (That was dumb) Innovate PSB-1 to monitor my boost and AFR all in one on my vortech v3 fox. Carefully wired it up and it was toast. The tach signal from the coil was making the thing reset itself, once cut it was stable but none of the readings were correct. I called support and they were at a loss, so I sent it in for them to diagnose (pending reply, said 3 weeks at least). In the mean time I got a great deal on a verified new guage head unit. Since the map was already there I figured YOLO and the price was right so pulled the trigger.
Guage arrived with the factory pre-stripped wire leads in tact. I rewired everything, welded in the exhaust bung, and got everything routed nicely. Ground is a chassis ground (sanded clean) inside the car under the dash. Power is a tap-a-fuse from 6 (then moved to 18 when troubleshooting). Ran a new tach signal directly to pin 2 of the TFI (splicing that wire was so scary considering how finicky those are). plugged up the serial cable and map to the proper proprietry plugs and began the calibration settings as described.
With the second install I really took my time, tried to research well and slowed way down. Every connection was heat shrinked with quality wire pigtails. I only stopped short of wiring in a dedicated relay (on phone with support they said "you can but typicaly not really needed"
Step one is key on, O2 disconnected for 30 sec and guage looks good, reacting as expected. Next was plug it in and key on and wait for guage to read "HTR", then "CAL"
It never comes on and the volley of explictives begins. I got so pissed I had to take a 30 min break at this point.
Revived, I got back to it, cycled through the screens to be sure no error codes. Chalked it up to a bad wideband sensor, as that can certianly happen. No change......
Moving forward I planned to go grab a new sensor today and keep validating, at least I would have boost and a more accurate tach.....right? Once I turned the key the unit started glitching and restarting immedietly. This is what the old one did before I cut the line for the tach signal but that was on the negative coil, this was spliced directly into the tach signal wire so really had no idea WTH. Cut the tach wire at a place I could splice if needed and when powered on and car running, the unit stays stable.
Take it for a test drive, screen registers no boost. The head unit and the map sensor are both brand new.....
Please, If im an idiot, I'll happily take that over having to cut this all out and start again.
In troubleshooting, the only stone I think is yet unturned is to try the tach wire behind the dash instead of the one at the TFI (should be same signal though) and wiring it to a dedicated relay, which I have, but support already said that is likley not necessary. I would really like to get this working, not just the time and money already invested but until I have this monitoring, I cannot get my party pulley to increase the boost.
ANYONE with ideas, I will try them all. I would be rather suprised if I just happened to get 2 bum guages that both powered up just fine but had all the sensor inputs dead. I'm hesitant to go get a new sensor before seeing the guage see SOMETHING for any sensor.
Please help
