A couple maft pro problems:

[GotTurbos?]

The first problem I'm having is that my wideband is not reading correctly, its a brand new LC-1 that I bought along with the maft setup. Its numbers are way off of whats actually going on (showing ~7-10) and 7 when I just have the power on. I redid the configuration and made sure it was set on LC-1 and it still does the same thing.


My next problem is with my TPS signal, 0% throttle I'm at .45 volts like it should be but at full throttle I'm only at 3.5 and I heard it was supposed to be ~4.5. The tps was recently adjusted so that shouldn't be the issue.


And while I'm making this thread... does anybody have the update.exe and the loadxxx.bat files for 4.8x?

Thanks in advance,
Jon

follow the instructions for the calibration procedure.

common problem. readjust the TPS or live with it....it doesn't seem to affect performance.

Which output did you use for the LC1 into the Maft pro? One is setup correctly and the other is not.

The only reason I suggest this is because when I had mine hooked up incorrectly I was reading those types of numbers

 

[drjonez]

good point. be sure you're using analog 2.....or be sure to scale the output you're using appropriately.

 

[GotTurbos?]

Okay, so I did both the calibrations that Innovative said to do for the LC-1, and noticed no difference. I'm not exactly sure what you guys are referring to when you say use analog 2 so if you could be more specific that would help me out.

The car also seems to be running horrifically rich, and that is with main scale at -20%.

I can post up all my settings, just let me know which ones you want to know. Pretty much everything I have is copied off of another member's setup with a 60-1 and 550's.

[drjonez]

the LC-1 has 2 outputs- analog 1 (yellow wire) and analog 2 (brown wire).

the MAFT pro's LC-1 setting is expecting the default output of analog 2 (0-5V).

copying someone else's settings isn't the best idea.

what is your fuel pressure set at?

 

[GotTurbos?]

I did everything I could on the maf and it does nothing. Set Aux to 2, did nothing, changed the afr source and all it did is change the number that it would show, but still wouldn't "measure" anything. FP is stock.

 

[drjonez]

so which output are you using on the LC-1? let's solve 1 problem @ a time....

please list ALL mods....

 

[GotTurbos?]

It was on the yellow, I just switched it to the brown. Now I am getting an active reading which just seems to be a bit off. Definitely a huge step forward. I updated to 4.8 a couple hours ago and the car is doing much better. I'm going to try and do another calibration on the sensor and see if that makes any difference. I'm typing from inside the car right now and it is showing it is idling at 8.7-9.2 afr. It is definitely idling rich, but not that rich.

Mods are 60-1 ct, 550's, mhg and arp's, 3" exhaust but on a stock elbow right now, full 2.5" hard pipe kit and 24x12x3 IC.

I really do appreciate all the help, I might be moving slow, but I'm definitely moving forward.

I should also add that I have the blue and white tapped into the ecu for a ground, I read some about people having problems with them not being grounded to the same place so I'm not quite sure what would be causing my readings to be off at the moment.

Ground LC1 blue and white wires to the chassis. This solved one of my problems. See the following thread ...

[drjonez]

yup. you never want to ground anything @ the ECU due to different grounds- power ground and signal ground. chances are you're attached to one of the signal grounds....
