Default Question about which chips I can burn with burn1

ok well normally i burn atmel 29c256 chips with my burn1, but yesterday i was tuning my friend's car using turbo edit and the chip he had in his ecu was i believe a 27SF256 or something like that. I stuck it in my burner and tried burning it with the tunerpro software set to burn the 27SF512. I figured why not...if it doesn't work then the car will just throw a solid cel. So i burned it and suprisingly it worked. The car started up and ran. Now my problem was that at certain rpm levels i simply could not lean his car out. Like from 5000-7400rpms the car would nosedive into the low 10's afr range. Could this have anything to do with the chip? Should I try using one of my 29c256 chips? Maybe is it not editing a needed portion of the chip and thats why my changes aren't doing anything?

Nothing to do with the chip. The chip you used is just 1/2 the size of what the burner burns. As long as its started in the correct Hex position you will be fine. What car were you tuning with the TunerPro? I do GM stuff to, I am curoius.

sounds most likely like a mechanical problem

...or you could have been changing area of the map it wasnt running in...i did this a lot when i was first starting out

but if you were changing large portions of the map and it wasnt leaning out...may be a fuel pressure problem (back up in the return) or some other issue.

logging anything with ECUControl or your LM-1?

I use tunerpro to burn all of my honda chip stuff. Its recommended on the moates.net site to be used with the burn1 hardware.

As far as changing the position that it was running..i'm not sure. What i did in the software was went to the burning section and then switched the chip selection from AT29C256 to 27SF512. The chip addressing start adress stayed as 000000 and the end adress changed from 007FFF to 00FFFF. I'm not sure what any of that adress stuff means though...

What exactly is ecucontrol? I haven't heard of it.

When burning the 512 chips, the start address needs to be 08000

in the tuner pro software if I switch it to the 512 chip it automatically sets the start adress as 000000. Also the chip i was burning was a 27SF256 i believe. I just tried burning it with the 512 option to see if it would work. The car didn't throw a solid cel and started right up so i figured it worked.

ok yeah well that would be right if you were using the 256 chip...if you use a 512 chip though, it needs to start at 08000

512 are double the size but still has a first address line of 000000...the end of the first 256 bytes of data is 007fff

the beginning to the next 256 bytes is 008000 and the end is 00ffff

im just beginning to learn about hex
