tunerpro rt file

Has anyone used this program on a 746 computer? I have a 91, 305 TBI that I am playing with and am looking for a good data stream file. The one I found seems to give wrong coolent temp numbers and some other problems.

Where did you find the one you're using? Why not fix it for everyone's benefit?

Find the template for your vehicle here:
ftp://diy-efi.org/pub/gmecm/ALDLstuff.zip

And use the info in the template to fix the ADS file.

Mangus,
Today was my first time trying out the TunerPro RT software. I got the data stream file from Moates site. I didn't know that these templates were around. I just took the original file and added a table like the template uses instead of the calculation that was used in the original. It fixed the problem with the coolant temp. I like how I can play my log back with the new data stream file and see the differences. I was afraid the software recorded calculated values instead of raw one.

Remember that the cts and iat aren't converted into an easy to convert value for the ALDL stream. It is raw a/d and inv a/d meaning you have to use a lookup table for it to be accurate for the whole temp range.
Does the ads file you're using use a lookup table or a formula for cts/iat?

That was exactly the problem. I think someone looked at one point, came up with a formula for it and went with it. Since it is an inverse A/D funciton I used a table.

Cool! Once you're done flushing out the issues with the file, can you email it to me? I'll put it up on Craig's site (where you got the original) to alleviate such issues for others.

the MAP is also in volts dc, so I just put in the correct gain and offset that we use in Ccom for the GM 1 bar map sensor. This way is makes it easier to correlate it to the tuning parameters. After I get this all tested I can post the data stream file somewhere for anyone that is trying to tune one of these computers with the TunerPro RT software.

Be careful. Use the hack and the ram, the hard work is already done for you;
From the hack; ALDL datastream
Code:
LD41A:	FDB $0023		; 4. coolant
$0023 is RAM (as is most of the ALDL datastream) so going into the commented ram it's said that this location is;
Code:
L0023	EQU $23	" coolant, 1k pu, inverse, adc cnts"
Inverse it is . The lookup table is in the hack but I'll post it here.
Code:

From the same sources the IAT is A/D not inverse.
MAP is $002A which is raw voltage. From some source, I forget where, I've got the following as a lookup table.
Code:
1 BAR	
Voltage	Kpa
4.90	100
4.40	90
3.80	80
3.30	70
2.70	60
2.20	50
1.70	40
1.10	30
0.60	20
0.30	10
Notice it isn't a linear formula. The other more advanced option would be to change the ALDL datastream to something like L0025 EQU $25 " s/d map, KPa = (N * 0.3125) + 20". This is limited to ~99.6kpa but it's used for the VE and Main SA lookup tables making it slightly more accurate (as if if would matter with the slow rate ).
