okay im converting my obd2 to obd1 so i can modify settings myself. I have a 96 z28. What type of connector will i need to hook my laptop to the car. Is the odb1 and obd2 connector the same. Ive been reading through the posts and cant find anything.

 

You still need an OBDII-style connector for the laptop cable. An OBDI converted '96 or '97 F-body ends up basically like a factory '95 F-body, OBDI PCM with an OBDII connector.

 

Thats what I did. I got a USB cable from akmcables. Works great.

 

what do you benefit from switching to OBD1?

 

it is a lot easier to work with the obd1 setup. I can download the software very easily and it is extremely inexpensive. I will be able to do all my own reprograaming with my laptop. If you have obd2 you either have to send it off or spend big $$$$$$$ to program it yourself.

 

isnt the lt1 edit availible for the 96-97 LT1? i believe its only $300-$500 for 1 pcm.

 

True, OBDII LT1edit sells for $450, compared to $200 for the OBDI version. But OBDI Tunercat can be bought for $90.

 

ok, so is there a performance benefit to either? or just peoples preferences and wallet depth.

 

I have the same question. What are the true benefits of moving to OBDI other then the cost of the software? Is OBDII a problem with a H/C setup? Something like a LE2 setup?

 

Some of the tuners state that OBDI is less troublesome to work with (less codes), and usually yields a few more HP. Some people complain that the OBDII misfire detection is set off by more radical cams.

I went to OBDI for the easy/cheap availability of interface cables and software.

In some states/juristictions that require emissions testing, they will plug into an OBDII computer to check for the PCMs readiness indicators - you'd fail that test if you had OBDI in your OBDII car. This is not a concern if you have to do a sniffer test instead.

Note that some people have issues with OBDI and high-stall torque converters - obviously not a concern with us 6-speed guys.

 

Go OBD1 Conversion with ION (www.madz28.com), and get your cable from Andrew (www.akmcables.com).
Mmm thats all.

 

will the light go on KOEO and go away with the engine running with the OBDII to OBD I conversion?
