    97 Aftermarket Tachometer

    Tried to use the one wire sensor in the driver side head that feeds the factory gauge. Kind of weird. I can un hook that sensor and the factory gauge falls to 0 and truck runs normal. When I connect that sensor to the aftermarket gauge, the truck struggles to idle. Makes zero sense. And the...

    97 Aftermarket Tachometer

    Update on the tach. I tapped into the white wire on the coil and tach works, but jumps around above 2500. I have a signal filter on order and will be here Thursday and will report back. Side note: On the water temp gauge, I tried to use the factory gauge sending unit with the aftermarket...

    97 Aftermarket Tachometer

    The factory oil pressure and temp do not read correct either. Changed oil pressure sender and both temp senders when the engine was built a few months ago. I am not a fan of factory gauges because of this issue. And besides, I like aftermarket gauges because they look cooler lol.

    97 Aftermarket Tachometer

    Have not seen much info on 96-98 Vortec trucks with aftermarket tach. Working on tach, water temp, oil pressure, and wideband install. Reading different things on the web about tapping into the tach signal wire, but also some people having issues with truck not running right and trans not...

    I cleaned the throttle body and blade real good before assembly but I did not remove the tps or iac so yeah I guess I do not clean it as good as I thought. You know what I’ll be doing tomorrow. I have a spare that I may take apart and clean. With everyone’s help we will get it. Thanks for...

    411 Swap 383 Vortec Newbie To Tuning. Where To Start?

    Okay. So a quick scan with dashcommand showed tps 0.4* and 145 IAC count. First started adjusting the screw clockwise and saw the tps increase but not much change in IAC. Slowly backed off the screw counterclockwise to 0.0* tps and the IAC dropped to 112-114 all at hot idle. That throttle body...

    So what does it mean if the wifi scanner is showing 130+ IAC counts? Someone jack with the set screw before I got the truck?

    At least as a back up, I have a WIFI scanner and Dashcommand with the PIDs so it can display IAC Position [Counts]

    Thanks I will check that out tomorrow. That is if I can get VCM Scanner to work again. I have an open ticket, so maybe they can get it figured out by tomorrow. Here is what they sent... Please provide me with an infolog while connected to the vehicle ignition on. Have you tried repolling for...

    411 Swap 383 Vortec Newbie To Tuning. Where To Start?

    Yeah, I put the stable version back on the computer. Although it does not show MPVI3, just the MPVI2. When I contacted HP Tuners when I first bought the device, they told me to download beta and look for daily updates. I did not know that they would push multiple updates a day lol. I will...

    I did. I also checked for latest version of beta and updated that again. Did at 10am this morning and another update this evening. Restarted computer again. Resync my device. Hooked back to truck. Connected to vehicle. No values will display. It worked the other day when I started this thread. SMH.
