I purchased a 93 z28 with an 67mm STS turbo I purchased everything from moates to read and burn chips I even copied the chip in it and burnt a new one because the prongs on old one about to break but when I try to read or edit the tune none of the injector sizes or anything in the bin reads what it should I used the $DA2 I tried a few different ones and none is right any input on what could be wrong would be greatly appreciated Laney
never seen a DA2 fbody. you probably have DA3. why do you think it's DA2?
see this thread (use the XDF at the bottom of the thread) http://gearhead-efi.com/Fuel-Injecti...mation-DA2-DA3
Im sorry I meant DA3 I can read other stock bins but not my bin or tune I really dont understand why I replaced the 24lb injectors with 60lb and now I cant modify pw or anything please any advise on what is the problem car floods to death now afraid to run it dont want to wash down cly walls. stuck at this point
Maybe you can post the bin and xdf you are using. That way we can check what`s wrong.
Are you sure it's the right PCM? If it's been so heavily modified, isn't there a chance someone swapped ECMs too? Having a totally wrong XDF would also explain it.
But agreed with kur4o; just post the BIN.
I appreciate the quick response from everyone Im sure I have the right pcm I own and run a auto repair shop for over 30 years so I do understand how everything works I have and use diagnostic tools but have never try and modify a pcm and back to it I purchased this 93 z28 thinking I could do the programming after wacthing some videos and a lot of reading so I go to moates and purchased emulator a burn2 aldl cable when i first got the car it would take a fit and not rev over 4500 rpm so I purchased a used 16159278 PCM $750 so I actually have 2 I repaired the old one I will post the xdf and bin from my pcm it has some kind of tune the owner didnt know who tuned it but it ran pretty good just not what I want so I replaced fuel pump with A 355LPH and 60LB injectors now dont want run at all flooding bad so Ill go and find out how to post what I have thank you guys so much
Attachment 17397 and Attachment 17398 I tried this one you sent also none will work
That bin is full of garbage data f3 and 33. I think you should revise the reading method. You can also read via aldl line with flashack program. But writing back is another case.
I used a burn 2 and read memical and chip why is it not reading correctly could it of been tuned with hp tuners or something like that causing the problem Im kind of stuck now I have another stock pcm should I try and make a whole new tune I dont even think Im capable of doing. get it good enough to get it back running and not blow up any advise is appreciated Laney
Maybe using non optimal settings during reading the memcal. Try contact moates for troubleshooting. Or a complete step by step of what you are doing, so we can spot some trouble points. There is read and verify so it is very hard to read garbage bin without knowing it.
i agree something is being done wrong
show us a screenshot of your settings for reading
and a picture of how the chip is inserted into the burn 2 as you are reading it
maybe your chip is inserted into the zif incorrectly, which is really hard to do because moates puts instructions right on the thing and then it comes with a manual with a picture showing how to insert the chip
also give us a picture of the chip itself nice and clear so we can read the numbers
Ok I will try and record the whole process as I do it and post for you guys to help me figure out what I’m doing wrong
I hope that I am doing something wrong and you can set me straight I’ve never really posted or anything like this before I am so appreciative that you guys are willing to take the time to try and help My daughters 16 mazda 6 is acting up so soon as I get it scanned and get it diagnosed I will get the video posted on my download thanks again
awesome. good luck with the mazda, i've done that dance.
like kur4o mentioned you could try reading the bin with my flashhack tool if you wanted, over the ALDL port (see tool in my signature), it's free.
it has a tool called 'aldl universal read'
since it's a 32kb bin and the device is f4 you have to go into the parameters tab and set:
device id to F4
memory size to 8000
read start to 0
read end to 7FFF
it's basically using your ECM as the prom reader
but it should read with your programmer too... so lets solve that problem or it might have trouble writing as well.. flashhack wont help you there.
Well I set everything up and started recording the whole process and when I went in to parameters it had downloaded the tune only thing its shows injector as 30s and maybe they are now I kinda need help setting the injector offsets its really hard to understand the pw settings in the XDF I've done a lot of reading but there's very little out there on this 93 pcm and how to set pws Im new to all this the reason for larger injectors is the car just doesn't have the power that I think it should I have a 67 camaro with a 383 flat tops pro comp heads that seems as fast or faster definitely more torque but any help on how to set injector offset would be greatly appreciated I already appreciate everyones interest in helping me I'll post the tune again see what you think Laney
Attachment 17403 Attachment 17404 And I forgot to say that the injectors are ebay chaep so very little info about them Attachment 17405
Let me know what you think about the tune that’s in it and can I just modify the PW and timing and get the power I’m looking for without destroying my engine It’s took me a couple months to get it where it’s at a pcm a distributor and new plugs with close gap to solve the no run and then no rev past 4500 rpm I assumed once that was solved I would be happy with it but it must have a soft tune I have a line lock and 2step for it also when I get the tune correct but just back running with these injector’s would be a great start thank you guys so much you have been a blessing to me don’t know what I was doing wrong but if not for you wanting me to video it I would have not got it done

i did get the tune downloaded but now i installed comp 467-13 cam and 1.6 rockers bosch 70lb injectors and having real trouble getting it to run half way decent tried $EEhack trim analyzer but still runs lean and rough have a lot of logs if anyone interested in helping me out on tune I would greatly appreicate it thanks Laney
