96-97 ECM swap FAIL

[payback]

Everything pretty much still applies, just ignore anything they say about boost, or any boost settings they change. You still should do a VE tune and try to stay away from WOT during it, and then after thats done move on to the MAF tune. The VE tune you will see can make the car run much better at idle with the more agressive the motor gets. Mine was a bear to idle before with my cam, but now since I've done a decent VE tune its gotten much better.

Also for NA there is no need to use 93, abundant or not. Its at every station in CT, but I still put 87 in there if I'm not running at the strip. Also as noted in a N/A application it will gain you nothing if you have no KR... They speak of 93 tunes a lot in the guides due to them all being boosted, and mostly its referring to just a bit of extra timing to take advantage of the knock reduction characteristics of the 93.

yeah youre right, the car runs amazingly well as it is and any gains would be too small to warrent it. so i'll just leave it alone until the new motor goes in, then ill have to tune it for the cam.. gotta bite the bullet&do the build myself. thanks for all the help much, much appreciated!

honestly...i just want to get more familiar with the DHP unit, i dont have too much longer before im going to need a full custom tune, so...i better get crackin. its not necessary to tune it in for higher octane, it is available here in NY abundantly though.
i have the guide, and it has great info and all but..i hate how it seems to be geared toward that damn dinoL67...it just makes things more confusing. they really should have used an n/a motor as a base. dont really know where to start lol.

Well to add to all of that, if you don't have the compression to necessitate 93 octane then the tune for it is useless... The only thing you'll gain over a higher octane is being able to run more timing, and you can already run these engines at a very high advance with stock compression running 87 or 89. I've been able to run 28+ degrees with 87 in my car and that is 9.15:1 compression, Stock 3400 is only 9.5:1

Now if your were boosted I can understand the octane requirement, and or tune level. They will do that with boosted cars, and once again it simply means there is a bit less timing in the 91vs93 tunes, and quite possibly a little leaner too since with the timing drop you wont need it to be so rich to prevent detonation.

I agree. I would tune for midgrade at most. The highest we can even get around here is 93. I'd hate to see you tune it for 93, then go somewhere where 93 isn't available and have the car run like crap. If its a DD, tune it for a lower octane.

Before I spend a lot of time here even trying to help, I will ask ONE thing.

Why are you trying to tune it for 93? What do you expect to gain over using 89? Or even 87

Need to do a few more logs with TP scanned, and possibly FT Cell. But I did notice you have very high negative trims... Whats done to this car?

yeah, i think thats because i had just swapped the ECM, i did one more scan with TPS and FTC but i must have removed MPH. i still seems even after a 600 mile trip the LTFT's are still high negative, at least to me.
the car is 100% stock other than a K&N cone and a '01 malibu intake tube, which is more straight and not bent like stock and the IAT sensor closer to the TB. shes got 232k miles on her.
the only thing i really wanted to do is get it tuned for 93 octane and remove the limiter, which i think is already done because i checked all the limiters in the bin file they were set to 255mph. apologize i could only get one scan in, also i just remembered i have been running the car on 89. dont know if it would make that much of a difference or not.

Well, used a different '96 ecm and did a full write, worked great, no bugs whatsoever, 20 minutes later i started with a couple of scans...dont know if theyll work or not. i have yet to venture into tinkering around with anything.

LOL, its ok.

and yes for most of the tables that are exactly the same you can copy them over from the 96 file to the 97 one, Some differ in scale, so you will have to take what you can, or just do a fill entry, injector flow rate is one. The beretta file only has one static value, The Venture one has a table that goes with the MAP scale, so you can later in life, figure out what your injectors actually flow when the modulator reduces the fuel pressure. And you would do all of this before a full write.

Don't even worry about what OSID comes on whatever ECM you get, just DL the 97 venuture file thats supported and then just do a full write to whatever 058 ecm you get "using ecm vin" and it will write over just fine. You really only need a vin handy if your ECM gets interupted during a write... but even then I'm not sure if the vin has to be specific to the year ECM it is... I've never tested writing a 96 vin to a 97 ECM... I should try that someday and see if I can get my setup to match.

One table you cant forget in the venture file is the Drive sprocket ratio setting, you want that set for 1.12 if you have a stock beretta trans... if you have a 3.29 trans then it should be 1, and if you have a 3.69 like mine it would have to be .89 It all depends on which drive and driven sprocket you have in it.

That is not a 97 venture ecm... that's something else. Do not use it again. Get the 97 ecm that ends with 058 in the service number. Its very easy to find the right one.

Ventures don't have VATS enabled by default anyways so that's not an issue.

Also why do you need the vin?

You need to get the supported Venture bin file that's on the powrtuner website so you have a file you can flash, but before you even do that you need to adjust the fuel injector flow rate otherwise it will not run right, and you will need to adjust the trans tables so it will shift properly.

thats so weird, its possible the yard marked it wrong though, ive seen '99 berettas there before lol.
in any case.. youre saying i need to make those changes to the bin file in DHP BEFORE i do a full write. i have the stock '96 file so i can basically use that and copy those values into the '97 file, then do a full write.
thought i might need the vin in case there was an OSID problem
also i looked over the 058, that would have saved all of it right there. i have a thread you posted bookmarked for ref. so its a huge for me. i hate feeling like im wasting anybodys time.

yeah, ill have to get a pic of this ecm its odd looking, i looked at a few other '97 ecm's they were identical to mine...this one was not, i dont know what the differences could be but im not even going to bother with it, im going to just get another '96 and start with that since the pinouts are the same and obviously monkey'n around with that is alittle outta my league at the moment. trial&error

[SappySE107]

I disabled VATS on the 97 PCM that I had swapped into a 96. I have no idea what yours is doing though.
