Re: Connecting tunepro rt to ecu
I checked those and one was .05 off and the other was .01 off. changed the values and still not right. Going to check the earth for the mtx

Re: Connecting tunepro rt to ecu
I set the values exactly the same as the default setting for the gauge and still not right. Checked the earth and that was perfect. Gunna see if one of my old laptops has a serial connecter so I can double check the mtx programed defaults. Cant work it out

Re: Connecting tunepro rt to ecu
No luck on the laptop I could see any reason why the defaults would be different in the gauge. I am at a loss. Any ideas???

Re: Connecting tunepro rt to ecu
Have you checked the settings in the adx match your wideband?

Re: Connecting tunepro rt to ecu
Is that the same as VE LEARN PARAMS for wideband 0-5v? If so yes.

Re: Connecting tunepro rt to ecu
seems innovate have done something to there kits recently, i have had 2 people with MTXL's in the last few weeks where there was differences of 1 or 2 AFR between the gauge and datalogs, found that earthing the mtxl to the pcm/ecu case on one of the hex screws fixed the issues, must be circuit changes perhaps in the latest revisions with how it compairs to earth and feedbacks 0-5v. This is also stated in some of the doco's now that it should be earthed to the item where the 0-5v output is connected to.

Re: Connecting tunepro rt to ecu
Ok. I will give that a try. I did notice that the case had about 200mv voltage drop from the body earth with the ignition on and engine off. Should I keep the body earth and also earth the case to the MTX-L? or just use the case as an earth?

Re: Connecting tunepro rt to ecu
Ok, I think I have solved the issue. Connected the earth from the MTX to the case of the ecu and instead of the readings being 1-1.5 out they are only .2-.3 out. All I did after that was bring down the 5v setting from 22.40 - 22.00 and now the gauge and tunepro are reading the same
Thanks for the help!
