At my wits end with this one. I've been using tunerpro for a couple of years for minor benign mods, while I never claim to be a professional. Regardless, before this current build, I used tuner pro on my Beretta using the stock code, the correct xdf and the correct adx. I did this all the time, and through minor modifications it ran great. I would just alter the bin, upload it to the emulator to get my fans coming off and on at the right times, etc. Then put the bin on my stock chip that I had thrown an atmel into, and moved on. And I'll lead with, to inform the reader, i'm not a complete retard at this, as a matter of fact I was messing around with my buddies trucks quite a bit last summer.
Fast forward.
for what it's worth, it's a 1989 Corsica hatchback. Five speed swap, LG5 turbo. LS springs, roller rockers and it's got a three-bar map in it. '730.
One day, I decided that I wanted to go out there and mess with the tune a little bit, I was still in the early stages. The dog chewed up my extension cord (bad LT batt.), So I took my prom into the house, plugged it into the mini programmer, pulled the bin, did the modification, put the bin back on the prom, went outside and stuck it in. the fans come on as if you're in diagnostic mode, and the check engine light flickers. No start. All I did was change fan temps because I put a 160 thermostat in. So now I'm confused, I go back in the house and mess with it some more. After a week or more of research, people are informing me through the posts that I read, to make sure the checksum is disabled, or set at AA. It was not set at AA, however I'm going to point out that I've done this process a million times it seems, and I've never touched the checksum or any of its parameters. I've never had a problem, and I'll defend that fact to my grave. But all the forums I'm reading are saying that that's impossible and I should have been disabling it or it would not work. I disable it. At this point I'm back outside with the emulator and a new extension cord, trying to figure this out. No check engine light at all/no run (but no fans) when it's set at AA. Fine, I'll throw in a two-bar map, emulate 8f, and see what happens. Same thing, fans come on, have to disable the checksum, wash/rinse/repeat. I have unaltered bins saved, same thing. Every single one. it doesn't matter whether I physically burn it onto a prom, it doesn't matter if I'm trying to emulate. You can set aa, and the fans won't come on and the light won't flicker but the car still does not start.
Fine, let's throw in a one bar, just to get it to idle, make sure that I'm not completely stupid, I disconnected the turbo. Same thing, correct xdf, correct bin, correct adx. Load her up in the emulator, upload it and of course wouldn't you know it. Flickering check engine light with fans. What is going on. fine even though I know it's not going to work I'll go disable the checksum, well maybe it's my xdf, but there is no checksum table anywhere on the OEM bin. I'm using tuner pro 5, ostrich emulator, and whenever I need to burn hard copies I'm using the mini pro programmer. My car is completely disabled, literally nothing I do will make it run.
Well wait, maybe it's your prom. Maybe it's the ECM!
I have spare parts, 6 ecms that I know are good, same problem. Also multiple compatible chips with Atmels. No go. Here's the funny part, I load all this up and with the key on I get acquisition. Every single sensor seems to be working correctly, temperature seems to be accurate. So it's not like I'm not able to communicate through acquisition. I've read a few things about settings in tuner pro, that I cannot find. And now I'm in this loop where no bins are working, don't know what to do. I know someone's been through this before, tell me what I'm doing wrong!
