Need tunerpro XDF and ADX for 1228747 AKWA

[EagleMark]

I was talking about the spark advance value in the adx file. It was something I was trying to do on my $42, which is identical to your $4f except one byte change. It just won't work with this ECM data.

I checked the ADX and it is correct? So you may have a bad CTS? Or have you moved it to another location to install you temp gauge?

[1leg]

More then like the wrong year sensor. I,ll check it.

Can we make spark adv, active with this ecu? I would like to see the data.

[EagleMark]

It's just not in the data stream... don't know if a guy good enough at hacking bins could make it work, wouldn't be worth the time really, just play with timing and watch for knock counts and back off.

CTS are pretty standard, but I have seen this increase in temp and decrease in temp because of them mounted elsewhere and use the hole by thermostat for their temp gauge. The water flow their gives ECM info it wants to see! More important then a temp gauge.

[1leg]

Cts is in the stock location, I had to install a new one when I put the engine in. The temp gauge sender is the stock one, and is in the stock location. I will look to see if they made different ones, I guess It could also be a bad sensor.

Here is what i got with testing, My multimeter sucks but I got 221-229, with my infrared temp gun it read 145-150 on intake right next to the sender. hooked up TPRT and the logger shower 171. I started the truck and watch the temp using the logger and my infrared gun. Temp stayed right at a 25-30' different between them.

Conclusion: temp sender is bad. The MM reading and the temp on the logger are in sync, but the temp sender is reading 30' more then the actual temp as read by the infrared and stock gauge. I need a new sensor any suggestion on brand?

With the sender reading wrong how will this effect the tune?
Would a heated o2 sensor help me get into closed loop sooner or is it a waste of time?
Next up I will be resetting the IAC as described on TGO website, This engine seems to idle really low in drive, could be the cam.

[EagleMark]

CTS sensor is pretty cheap no matter what you buy. AC Delco or whatever factory brand is would be best choice. Yes running 30 degrees to hot to ECM will effect tune!

If you have headers and the O2 down in the collector a heated O2 sensor will help. But with a good tune I ran an unheated O2 down there and never noticed the short times it was open loop. But when your data logging you want to make sure you are warmed up and in closed loop before starting recording or you'll just be filling the box's with 128s and skewing your real BLM numbers.

I'd do a little idle tuning for that cam before I did a min air reset...

That 1228747 is a truck ECM, trucks are known to stay open loop longer, may have some parameters to keep it open loop longer then my 1227747. My O2 is in exhaust manifold and I go closed loop within a minute or so cold start in winter...

[1leg]

i'll get a new sender this weekend from the dealer.

The headers are the shorty style, but the O2 is down after the y in the y-pipe. This is the way it was stock so when i had the exhaust done with a flowmaster y-pipe i had them place it in just about the same location.

[EagleMark]

Wow that's a long way. Actually way further than where an O2 sensor is supposed to be located. No bungs in the shorty headers?

I would say yes a heated O2 would help.

[1leg]

Got a new Acdelco sender i will install tomorrow morning. I will look into the heated O2 and get that in there in the next week or so. I will be moving soon so i want to get this thing running a little better before that happen.

[1leg]

got the sensor installed, I did check it before installing seemed to read the same as my infrared gun. But the logging it now reading about 25' higher then my infrared and gauge in the truck.

What do you guys think? could the xdf/adx file be wrong for my truck? I don't under stand the code yet to be able to check it.

[EagleMark]

It is reading from coolant flow, your infered heat gun is measuring metal on outside and being cooled by fan?

The ALDL file the ADX is made from only has Celsius look up table. Is the Celsius reading correct?

The Fahrenheit is a lookup table that is converted from celcius but works properly on my $42 1227747 and others. It just spits out a temp for byte count from 1 to 255... This is what is in the adx. everything is offset by 1.

Looks like C' and F' are matching when logging, Could some thing be wrong in the wiring on my truck? My buddy is going to bring over a better Multimeter and help me check out the sensor. I'm sure this truck is not running that hot.

[1leg]

Waiting on my buddy to show up, I was warming the truck up, it has a 190' tstat. pointing the gun right at the radiator inlet it went to around 195' and then started cooling down as if the tstat opened.

C' is 10' higher on the log then the gun.

I'll let you know the results after my buddy get here with his multimeter.

[gregs78cam]

couple things. temp gauges can differ from CTS by as much as 20 degrees depending on location, water pump flow etc. and IR guns can vary by a LOT depending on the surface it is pointed at. google emissivity.

http://www.omega.com/prodinfo/infraredthermometer.html

If your CTS shows proper resistance at both ends of the temp range then I would go by that. Your temp guage is just that - a gauge, not a meter - readings can vary.
