an AFC isnt tuning properly....We already know that.
But, unless he is attempting to compensate for larger injectors or other mods, why get an AFC? There is something that is causing the car to have this problem. By using the AFC to fix it, all you are doing is putting a band-aid on it.
I highly doubt your injector pulse rates have anything to do with it. they are controlled by your ecu. Having a bad ecu could affect this, but is probably not that likely. If you had a diesel vehicle it would be more common to have problems related to injectors or the pulse rate. What brought you to onto the idea of checking the pulse rates????
Have you checked your MAF, and for boost/vacuum leaks? Also did this happen after you swapped to a differant BOV or intake or something like that? if so put it back to how it is an see if it has the same problem.

lol well i didn't really go into trying to check pulse rates unfortunatley the eclipse didn't have many sensors to get readings from. he did just get a new bov on but i think he was having the problems before that my thoughts were boost leak, maf, or maybe some bad / dirty injectors. i thought the wierd pulse rate may have shown something wrong with the injectors but ya, it was just a random guess. i guess he had it checked out by a mechanic who said there were no boost leaks so the other cause would be the maf. idk does anyone have a maf we could swap out with to see if thats the problem or would the scanner show the maf reading wrong through low voltage leves or anything?

lol cant really remember all of it. like i said barely had any time with it. there really wasn't very much to monitor or nothing helpfull at least. thats why im giving you things like the pulse widths. the eclipse wasn't even giving us rpms or the usual things you would want to monitor. when i had my celica hooked up it was everything you could ever want and more. eclipse its like battery voltage and random things like fuel tank preasure. hopefully we can take it out again tomorrow though and i can get more time to check things

We have a MAF here to test. An O2 simulator simply shows the ECU that the cat is working correctly. It gives it a constant voltage reading like the second O2 would be doing.
Was this done at full throttle? I know when I tested it myself, it seemed to drive fine after a few minutes. Definately check boost leaks.

with the test pipe the check engine light was on..then i cleared it about 3 months ago and it hasent come on since.....but i need to find a stock cat for cheap first...because the test pipe doesnt do anything anyway..or just get turbo back 3 inch exhaust.....

From what Frank was saying you have your BOV duct taped on and you hacked up the stock plastic IC pipe to make it all fit up. For starters, fix that setup right and move on from there.

I believe that the ECU requires the O2 sensor to switch between .7 or whatever and 0 otherwise it will set a codenot the downstream 02. the down stream 02 usually doesnt change its voltage much. it doesnt switch from 0-1 v like the upstream 02.

It wasent me who hacked it....beaner did...he said he did that to lacey's gst and said it worked...
