Almost There, AEM Wideband about 10% off and New 3 bar won't read in VCM Scanner

[Meyers2211]

Hello everyone, After 3 years of building, I'm finally tuning and datalogging. I have successfully Added the AEM Uego Wideband into the Config File using the #1 input and #5 ground. I have both the HPtuners and O2 grounded at exactly the same spot. Unfortunately when using the PID it reads about 16.0 when at 14.7. So thats my first problem.

Second problem, can't get MAP sensor to read over 105kpa. I'm running the ZR1 3bar Map sensor and while its running good I can't datalog above that figure. When I improve the limit, it does nothing. I've tried the 2 bar and 3 bar pid's but can't make it show up.

Came a really long way from Tunercats to Hp tuners and i'm extremely pleased with the speed and flexibility of the program

Wideband - many have problems with ground loop offsets,
the "fixes" that involve messing with the transfer function
I believe are wrongheaded because the offset changes
with sheet metal ground current. Rewiring the OBDII
connector to improve the ground may be more effective.
Most effective is some more involved hardware but most
folks aren't ready to go there.

You must use the special MAP PIDs, not SAE MAP or the
standard OE MAP PID. The custom OS gives you some new
MAP related PIDs to use.

I feel your pain meyers2211. I just got mine rolling im no professional but ill tell you what I learned. first you need to select the correct pid for your 3 bar map in the primary table. then go into charts on the left and change the max value there will be a hi, mid ,and low so that chart reads that high. then go into histograms and histogram configuration. bring up tables that use map and click the folder icon and you should find pre made histograms that will probably fit your needs. be careful I had a meltdown from the same map issue. don't learn the hard way. i feel like i left a lot out but I hope this helps
