16168625 problems

[Midnightreaper]

Hi I have done a good bit of work with the $OD for my V8 S10 but now I am having problems with my 1993 Chevy C1500 350 TBI. It is running the 16168625. Every time I write a chip and attempt to run it, the check engine light flashes like a strobe light. I could be wrong but I believe that means a bad prom. I really need to fix this but don't know what to do. Anyone else have this problem and fix it? I am burning my chips. 27sf512 I believe is the part number of the chip.

Using the proper offset?

I am really not sure to tell ya the truth. I am not a pro at this by all means.

is that an E6 truck?

i seem to remember the checksum settings being wrong in a few of the XDFs i've seen for it...

just set the mask ID to AA and see if it happens again. if so, those settings need fixed.

Does anyone know if the pinning between the 16168625 and the 16197427 are the same? I have an extra 16197427 ECM and good files to use with it. Would just have to convert over some of the information to the $0D mask. Any thoughts?

i could probably email you the diagrams and let you figure out if it is feasable...

interested?

I did this and it seems to be working. Will it be OK leaving it this way or should I change something else too? Thanks again.

i believe the correct settings are

data start: 4008
data end: FFFF
store address: 4006
store size: 16 bit
data size: 8 bit
calculation: sum(no carry)

Does anyone know if the pinning between the 16168625 and the 16197427 are the same and if they would equally operate a 4.3 VIN W Vortec?

I have these settings entered and it is connecting but I am getting a bunch of errors as it is connected.

I am also having no luck getting the history (histogram) function to work in order to tune. I have tried everything I know but it will only fill the first column as if it wasn't reading the MAP or something. Someone please help, I am at the last stage before getting this inspected and running it and now I am stuck bad.

well, those are settings to correct the XDF, sounds like you're having an issue with an ADS or ADX...

if you're using TP V5, follow what i wrote in this thread, see if it helps clear up your issues.

Robert, I am having the same issue with tuning a 93 Silverado 5.7. Where do I make these changes? Thanks.

There are new xdf and adx files for TunerPro RT V5 available that this issue I believe is fixed. You can get the files here:

Thanks alot, that took care of that issue. I have been pulling my hair out trying to figure out what I was doing wrong. This may be a question for another thread but the VE table in the BHAR bin file for the 93 1500 w/350 truck I have been working on has values in it at almost 100%. I know is BS with a stock TBI motor. Any changes here are going to take some of the values to over 100%. Is this normal and will this be an issue? Thanks again.
