my autoprom does this once and a while too. I just reupload and it will take after a couple tries. I noticed this happens more so if I hit upload right after I initialize hardware without giving it a few seconds to do whatever it does in the background.
Might have to do with checksum disable, AA?
I have AutoProm and no issues, upload to emulater, verify and run it!
got it ,just waited a minute after intial like pj said .
Thanks guy and Mark I got Mr hyde running decent well at least Idles pretty good but Its got a maasive whistle under the hood around 15 inches of vacuum..sounds like riser blocks,so I guess im gonna pull the intake lol.One thing after another on that truck but do you mind looking at the log and see what you think thus far on it
Make sure that's not IAC whistle first!!! May need a little more throttle blade opening, reset TPS voltage, look at IAC counts. Can usually get a little more vacuum at idle with some more timing and/or raising idle a little too!
Sure I'll look over the data log, post it up and remind me what ADX.
1227730_8d.adx
started gettin a lil warm before i caught the fans not workin got it resolved and went on but I dont think that other than puttin a little timing in it, that it is pretty much a stock bin
I looked at your log. Couple issues that will help idle are IAC count is high at like 50. Need to do min air adjust. Open the throttle blades a little and get IAC down to 10-20 tops at warmed up idle. Half turn out. Turn off engine and let it reset and check. Hald turn out turn off engine let it reset and check. Or can do it properly by turning key on, crossing A and B of ALDL port to set IAC all the way in, unplug it. Set idle to about 100 rpm below idle in chip. Hook up IAC, clear codes and restart. Check IAC count.
TPS voltage is high at .73 May have to bend tab on throttle shaft or file out holes in TPS to get closer to .54. After opening up throttle plates above.
Other than that it's about 114 BLM so take some fuel out to get to 128.
How rich has it run for how long? May need a new set of plugs and O2 sensor. Get above done first and rev it up and clean it out.
Running TBI with 8D?
My bad. I took TBI out of throttle shaft. No he's running a TPI.
Will do sir and as long as you don't mind looking I will repost new log asap....... sad part is it runs 10x better now than it did and its not hunting idle either now
ok hate to sound stupid but rather be safe ....how would you go about removing fuel in tunerpro ...im asking because im new to this gm side and this doesnt look like no honda bin lmao, thank youQuote:

ok thats simple enough better for me to know than guess im right lol.....and is there not a ve table calculator for this?where did you see iac counts all i see is position, is this the same ? and why do i have no history in my datalogs on this adx??? just wondering thanks mark
IAC postion is counts.
Guess no one ever made the BLM history tables? Dave has made a bunch of them for excel but I don't remember any for 1227730? Going to have to learn math or learn how to build a history table to get std deviation...

awesome no problem ,the calculator has made me lazy lol .I used it on that tbi truck I was learning on and fell in love.Ok mark I leave yall alone now and get back to this but thank you sir
wow thank you very easy and done lol ,im liking tp more and moreQuote:
