I've gotten an autoprom with Tunerpro software from Moates. I have 2 problems; 1 I want to change the injector constant, but the only one I can find is in gals/hr not lbs/hr, any conversion? I went ahead and changed it a little to see if it made any difference and hit problem #2. When I plug in the autoprom or a chip I've burned the new program on it, the ecm acts like there's no chip-CEL on, fan running. I'm new to this so I may be doing something wrong, any ideas?

Thanks, Paul

 

Paul,

When you saved the modified .bin, did it do the checksum?

 

Grazie Dominic, When I shut down Tunerpro, it asks me to save modified bin, I click yes and an error message comes up saying couldn't save bin. The bin seems to be in the autoprom because I can download it later to my laptop and the changes I've made are there. This seems to be the problem because it never says anything about checksums. Frankly, I'm not sure what a checksum is. I couldn't find any definition in the Tunerpro software. I'll keep checking into it.


Paul

 

So Paul this sounds like its a TP issue not AutoProm. The bin is bad for some reason. Have you tried a stock bin for your car? See if that works.

 

It is possible that the bin file is bad. Where did you get it from?

Try loading a stock bin and verify that the definition file is correct for your application (86 vette?).

FWIW - I have the Autoprom mounted in the car and connected via ribbon cable to the ECM. I find it easier to make changes this way during the tuning process, rather than having to remove/program/install a new chip each time.

 

I agree, w/fans being on could be a corrupted bin file and occur from time to time, load a different bin., check proper, definition, data stream etc. You can also unplug to aldl and reboot program, reconnect and re-try.
Make sure it shows "initialized" hardware found, before trying to load a bin. file.

Checksum shows at bottom of program (in yellow captioned box), I usually go to file and "save bin as" to re-title, checksum update, and for point of reference which will create a new bin. Anytime you"save' there should be a checksum update.

I have found when you make many changes to a bin (in progress real time emulating/on the road ) that sometimes on re-loading a bin, or when stopping to make changes and then re-start the car, that I would have somehow corrupted the bin file. On re-start is when they usually would throw sys. light, fans etc. I will take all info and copy and paste to a fresh bin, re-load the new bin and all is well.

When chip burning you can check beginning and ending addresses (preferences), and check for correct corresponding chip number before trying to burn a chip (check direction of the chip when installing on the burner in the auto prom). When burning you should, first do a blank chip test, load to buffer, and copy file. You will get prompts when doing this telling you if chip is blank, file load success etc.etc.

 

I have an Ostrich, and basically IT is my chip.

 

Thanks guys. Like I said, I'm new to this and its like learning a new langauge. The def file (xdf in Tunerpro) I used was 32. Which is correct based on a table I found somewhere. I have the stock bin saved, so I will figure out how to load that onto the autoprom and retry.
Anyone have any thoughts on the gal./hr injector constant?
Looks like I have more homework to do.

Thanks again, Paul

 

Paul,

You should be able to convert gallons to lbs. Go to 3rd Gen and see about conversion formulas on there.

 

I reloaded the stock bin on the autoprom and hooked it up to the ecm. The car started normally. Made some simple changes while the car was running and everything seems to be OK. Not sure what I did wrong the first time. Now I need to figure out what to change to get the results I want. I wasn't able to get scan data to display on my laptop, but that shouldn't be too hard to figure out.
I've spent a lot of time on Thirdgen, lots of good info there, but haven't found anything about gal/hr injector constant.
Anyway, I feel I've gotten over another hurdle on my journey to tuning Nirvana

Thanks guys, Paul

 

Paul,

Take the changes you've made in the "corrupted" bin and transfer them over to the stock bin you have. Then save the new bin under a new name. Try that and see what happens.

 

Gas is 6.350 pounds per gallon

 

Hey Jim,
I found that number too, but the constant that came up on the Tunerpro software for the stock bin was .26 gals/hr, which comes to 1.65 lbs. Obviously that doesn't make any sense. I've been bumping the # up and the car is running better, but still too rich.
Are you going to Petaluma on the 12th? I think there are 3 of us cruising down together from Sac if you want to join us.


C-ya, Paul

 

I believe I've figured out the gal/hr question. apparently that constant is for the computer to figure mpg. The real inj. constant is labled single fire FI size. There are 2 of them and both must be changed to the same #. It would be nice to find an English/Jargonese translation book.
I'll try plugging in the autoprom tomorrow. I'll post the results

Paul

 

IT WORKS Now the fun begins. A big thanks to Mark at Tunerpro!


Paul

 

You've now completed the first step towards the journey of endless tuning!

 

now the search for the holy grail....and you thought you were having fun before

 

Yup - it's all down hill from here...

 

I'm going on vacation Thursday, so it will be a week and a half before I can get back to it. It runs much better now, idle and throttle response are much better. I still need to get aldl data working, I think there's another file I need to download for that. Then I need to get the LC1 wideband connected to the autoprom so I can datalog that along with the aldl data. I just have it connected to an ometer right now.
I still have a lot of homework to do, but I'm itchin' to get to the track and see if its any faster. My best previous time was 14.40, but that was before the headers, dual exhaust and 30# injectors. 13s maybe?

Thanks everyone, I check in later Paul
