Just got all the ute back together and give it it's first rev.
something funny going on, the tunerpro wideband reads about 1 AFR higher than the one in my car.
also my ve table is around 90% for everything but runs and revs ok???
Make sure the params "VE Learn Params - WideBand 0v AFR" and "VE Learn Params - WideBand 5v AFR" match the output of your wideband.
Wideband VE learn is a slow learn process - its not going to tune an engine thats miles out quickly. Your better off logging and adjusting the VE manually first to get it close.
blm params block learn minimum blm (currently is 110 units)
blm params block learn maximum blm (currently is 140 units)
when i am looking at the history and the blm table... should all the numbers just stay at 100? what does the 100 mean? it just puts 100 in every cell i rev it through?
and in the history tables, the injector % just says 100 too for all the cells. is it supposed to?
Is there any way to know if the ecu/wideband ve learn is actually learning anything? is there a set time somewhere for it to adjust stuff.
ok firstly, blms wont do jack shit when you have wideband ve learn on and will all show as 100.
secondly, ve learn will not work with a quick rev, you really need to drive the car and try and hold it at certain load points for as long as you can so it can adjust that cell.
having said that, if the gauge on the dash is showing 1 afr different to whats in the logs then your wasting your time using ve learn.....
i suggest reading the basic tuning guide which there is a link to in my signature below this post, it gives you pretty thorough instructions on how to get the basics of the tuning happening!
i would also suggest turning ve learn off, then using your blms or the wideband histograms and use them to get your ve table in the ball park, then worry about ve learn to fine tune it.
No matter what the question is, the answer is always more horsepower!
I was wondering why it hadn't changed anything since I have the back of the car jacked up and in gears simulating driving for a few hours with various revs and holding brakes etc hitting and holding cells but didn't seem like it was actually learning anything. I am rich accross the board with the high ve's and was hoping it would just lean them out for me.
that's why I was asking if the blm params were set wrong. at the min and max as above.
I just left them settings as they came in the download for v111.
I will have another read of the manuals plus my efi tuning book.
I was hoping to get a quick learn with the ve learn. (name is deceiving doesn't seem to learn anything even after a couple hours drive)
Did you click 'download' to suck the whole calibration back out the car? Whats on the nvram and what tunerpro has in ram will get out of sync when the ecu updates itself and tunerpro doesnt know about it. hitting 'download' is the only way to suck the ve table back out of the ecu. It does learn slowly though as its designed to not make drastic changes. Better to tune the recommended way instead of subjecting your wideband to the rich exhaust for as long as you'd need to make big changes.
Looks like the car is rich as. I have tuned a few cells and noticed the ve is up there with the right afr. does this mean my injector settings might be off... if the ve's look too high with the right tune in the cells.
I think i have the ve's safe enough to go for a drive now, so i will go for a drive tomorrow and log it then get the calculator out and adjust the ve cells compared to the history wideband log and see what happens.
Don't worry TTVN, I'll try not to let the smoke out on you for the timing.. lol.
generally you want to have the highest 100kpa cell at about 85-90, so if you find you are still lean and its at 100 then you need to change the injector rate to get it right, this might mean the whole ve table needs to be offset afterwards too.
go for a drive and do a log with it and post it up

The exhaust sounds wonderfull too, real nice loud cackle. lol.
