TGP Code Injector flow vs Base fuel constant - Page 2

units for sure. You were giving me hex. Get the a1.doc file off this site and go the egr vs bpc. You will see what I am talking about. You should get a .xxx value, like .155 or something. Thats the constant with the correct hex conversion.

TunercatRT certainly has TunerproRT licked in this area. As mentioned earlier there is a stand alone BPC listed under constants in Tunercat and it is not far from the value I calculated. In addition to that the car is running much better now as a result of changes made to that value to a little less than the value I calculated.

Since the engine is still running a little rich I believe I'll work on the timing increase a little more before pulling more fuel.

Do you know the formula for converting 104 units of manifold air temperature to degrees?

What hex address is it changing?

104 units? I dont even know what you are talking about now. what file are you using with tunerpro? The software is only as good as the definition file it is using.

Look up the TGP info in that and it will tell you what is needed to convert the units the $8F uses to degrees.

It's a definition issue, I had the same scenario with the MAP reading displayed as units instead of kpa. There is a formula for converting the units which can be inserted at the proper line in the def file to give the reading in the desired units.

I'm using the latest TGP definition file that I'm aware of.

Check out the file I posted. If your def is wrong or missing things that has the info in it to complete it yourself.

hmm, i dont use tgp code so maybe its different. The 2 fuel constants are used for the DIC only on the A1 and Df codes.

If your def is still screwed up and you cant figure it out post it up and I'll edit it with the right conversion equation so you can read your logs properly.

I wouldn't say it's screwed up because it works but gives what appears to be a raw value unless it's correct and has the wrong unit title. 104 is in the typical range if it is actually the temp measurement in degrees celcius which in this case would be over 200 deg fareinheight.

I just don't have the time to get involved with acquiring the knowledge necessary to make the proper changes myself at the moment. The zip file contains the ADS and XDF file that I'm using.

I'm not sure I'll be able to test drive it again before Tuesday considering the time it's going to take to change the turbine housings, add more heat wrap to the critical areas, install the speedometer calibrator, add the tach filter, water injection kit and change out another cheap shift cable from Advance Auto parts that could not take the heat eventhough it didn't touch anything hot. They must have copied the original only they used a much cheaper casing that's shrinking above a certain engine bay temp where the Fiero is known to be like an oven.

I'm on the laptop now so I'm taking a look at it with my ALDL info. It will log all the data the ALDL sends, but if the def is not right it won't convert that info into useable stuff. SuperDave had a def for $A1 and it had the IAT(MAT) temps inversed. I edited that def for him with the correct table (in the correct order) and it works great now.

If you have logs saved, you can try different def files to play them back. So a "updated/corrected" def will display the correct info from an old log. You don't have to re-record a log to do that. I will update in a sec after I look at it.

EDIT: A log would help me too so I could play it back and see the changes I make.
