I'm just running the Tephra 9417 option 3 ROM with very minimal tweaks. Should I upload it?
Was there any configuration that needed to be done to it? It was my understanding that it was very "plug and play" aside from scaling, etc.

 

You should fine then. Double check the settings one by one.

 

Any thoughts on what settings could cause such behavior? I've clicked through all of the settings, and checked what I believe to be relevant several times. That said, I'm new to evoscan/ecuflash (coming from ECMLink/DSMs).

Any thoughts would be much appreciated. I can upload the ROM if anyone cares to look at it.

 

u might as well load it up

 

Crap. Too big to attach.
I tossed it on rapidshare:

If that doesn't work I'll figure something else out. Or if you want to e-mail me, I could e-mail it to you..

Thanks for the help, very appreciated.

 

patch is fine.
3 options left...
1) wrong pin tapped
2) logging code is off in evoscan/mitsulogger
3) Bad Ground

 

With the 9563 v7 SD versions, the MAT is prepatched. You log MAT through the Intake Air Temperature option. The same one you'd previously have used for logging the IAT inside the MAF.

That's how mine works and I haven't changed anything. Just GM IAT sensor attached to pin 77.

 

No. You log 09 = fuel aka pin 77. If you're using the Maf/IAT for logging you log 11

Requestid09 = Fuel Temp
Requestid11 = IAT/MAT

All the patches and code a based on fuel. ONly for people like myself that have the gmIAT tapped into the maf/iat then we change all codes accordingly.

 

Sorry. I missed this section "With the 9563 v7 SD versions" ...you're right, they are prepatched for mat/iat/fuel ...same thing. Post up the code you're using for logging.

 

Is this what you're looking for? From Evoscan data file..
<DataListItem DataLog="Y" Color="" Display="Manifold Air Temp" LogReference="MAT" RequestID="09" Eval="1.8*x-40" Unit="deg F" MetricEval="" MetricUnit="" ResponseBytes="1" GaugeMin="-40" GaugeMax="300" ChartMin="-40" ChartMax="300" ScalingFactor="1" Notes="" />

I assume if you look at my log you see the same strange numbers? If so, it shouldn't be my evoscan..

 

Actually, now that I think about it, I still need to double check that I'm actually getting readings from the GMIAT and not the one in the MAF. It's still plugged in since I'm working on setting up my SD right now.

I think I'm getting the right reading though. My intakes temps aren't climbing much over ambient even while sitting and idling and I have an open air filter under the hood.

 

Try logging through mitsulogger

 

i have to try mitsulogger

 

Here's a picture showing the wire I grabbed...

 

Yup...pin looks good.
