Guest evilundisguised Posted July 11, 2005 Report Share Posted July 11, 2005 I heard there were a couple f-body owners hanging out here. I'm thinking it's time to get my ECU tuned. I'd like to play around with it myself, but the software (LT1-edit) is way too expensive so I've just got datalogging capabilities. With logged data, would a knowledgable mail-order tuner be able to come close to a knowledgable dyno-tuner? Are there even any knowledgable dyno-tuners around Columbus?

AngryBMW Posted July 11, 2005 Report Share Posted July 11, 2005 There is actually an entire board dedicated to F-bodys here in Columbus. Although we could help you, your question would be better asked on www.COFBA.org But, stay here as well. -Marc Quote Link to comment Share on other sites More sharing options...
Nitrousbird Posted July 11, 2005 Report Share Posted July 11, 2005 - No one locally tunes LT1's as a business - It's PCM, not ECU - The LT1_Edit for OBD-II cars is expensive. The OBD-I LT1_Edit is MUCH cheaper. You also have the option of tuning with Tunercat as well w/ OBD-I. Since you have a 6-speed, there really isn't a benefit staying w/ OBD-II. It is cheaper to swap in an OBD-I PCM and knock sensor (that's the only other thing you have to change) and buy the OBD-I version of LT1_Edit than to buy the OBD-II version alone. The real OBD-II benefit is w/ auto running stalls bigger than 2800, which isn't an issue for you - I've done all of my own tuning. That said, I'm FARRRRR from a pro at it, and wouldn't want to attempt it on someone else's car. My tune is basically hacking together tunes from similar setups and making it work for my needs. So far it has worked well and my motor is still happy. Quote Link to comment Share on other sites More sharing options...

I've thought about switching to OBD-I, but I've already sunk money into an OBD-II interface cable... which I guess I could sell off. Wasn't the switch from I to II also accompanied by the change to multiple O2 sensors? How would OBD-I handle my 4 sensors? Finally, do you post on f-body.org? I browse there alot but don't post much... Quote Link to comment Share on other sites More sharing options...
smokin5s Posted July 12, 2005 Report Share Posted July 12, 2005 the OBDII O2's work fine in OBDI (OBDI just doesn't use the rear O2's so just make sure to unplug them) Quote Link to comment Share on other sites More sharing options...
nathan Posted July 12, 2005 Report Share Posted July 12, 2005 I think you have a connector that is for an OBDI computer, but has the OBDII end, unless you put the money down on the LT1 edit cable (ouch). Quote Link to comment Share on other sites More sharing options...
mkent93 Posted July 12, 2005 Report Share Posted July 12, 2005 hey man, your interface cable is fine. I do hope you bought the newer USB interface cable rather than the serial cable. In my 97, I just bought an OBD2 interface cable, and had a guy solder in a resistor to the PCM board so I did not have to replace the actual sensor in the block. I use TunerCat (although I have not actually tuned)and other than the PITA USB-Serial adapter, everything works fine. The OBD1 was just plug-in and go. You can leave the rear o2's hooked up, it does not hurt anything because the PCM does not have an input for them anyways. Quote Link to comment Share on other sites More sharing options...

I browse there alot but don't post much...As said, the rear O2 sensors aren't used by the OBD-I PCM. Neither is the crank positioning sensor. I have never even looked around on f-body.org and was a member of Fbody.com 5-6 years ago before it turned into the crap hole it has been for the past several years.

I specified that I wanted a cable for an OBD-II computer, and it works to log data from my OBD-II computer, so safe bet is that it's for OBD-II. The 95's had an OBD-I computer but an OBD-II style ALDL port, if that's what you're hinting at. 97Z - I have the serial cable - is that going to be a problem? I just inquired as to whether or not my cable is compatible with tunercat software. I'm glad someone pointed that out, I've only been able to find LT1-edit before, which is pretty expensive.

nathan Posted July 13, 2005 Report Share Posted July 13, 2005 I am just trying to make sure that you do not try and load a program with a cable that is not compatible. The datalogging may work but AKMcables.com stresses that if you try and load a program with it will ruin the PCM. I believe tunercats for OBDII is $450, at least it was when they sent me information on it after it was released. Your best bet is to send the PCM to madz28.com and buy his converted OBDI PCM. I guess I would like to know where you found that cable though, because as far as I knew only carputing.com and tunercats sold the correct cables with their software.

I gotcha, I bought my cable from AKMcables, but i've only used it for datalogging, not tuning. I sent an email to TunerCat asking if my cable was compatible with their software, and the reply was that it was not. So looks like I'd have to buy the whole package - you get the cables/convertor, software (not locked to a single PCM - nice), and one vehicle definition file for $380.

98fiveseven1647545503 Posted July 19, 2005 Report Share Posted July 19, 2005 Im not sure. I do know i was quoted about $500 to get my 98 tuned if i get it cammed Your best bet would be call the shop and talk to Rick or Leo about dyno pricing. From what i have heard they are real reasonable on prices. Quote Link to comment Share on other sites More sharing options...
