^^ What??

 

Lol! ^

 

Great pics bro! Can't wait to see the finish product!!

 

Thanks Kytong.

 

Absolutely. Speed Inc tuned mine. I'm the first EFI Connection 24x car they've tuned, IIRC. They did a fantastic job.

Absolutely no cons. It's a simple, straight-forward install, with very high quality components. And your tuner will thank you.








^This. Worth every penny.

EFI Connection manufactures a cover that can work with a double roller, and stock timing covers can be machined to clear one as well.

 

qc97z - Not running a MAF?

 

Hell no! Speed Density all the way. It's easy to max out a mass airflow sensor when you're boosting 15 psi.

 

qc97z, very nice set up. Are those custom plug wires? And yes, I may also go SD for my present combo. Again nice job on the conversion!

 

Yep, they're MSD #32079, available from Jegs, Summit, etc. It comes with the LSx coil end boots and terminals, and a crimping tool.

Thanks for the compliment!
I also responded to your PM, FYI.

 

are those plastic zip ties holding the wrap on that last primary?

 

Lol, good catch. Yes they are. That pic was taken just after getting the header wrap on, and the parts shop supplied me the clips for a V6, and not a V8. So, I was short on the steel clips, and used the zip ties just to hold it on tightly to cure. They were replaced the next day with the proper clips.

 

Is there a big advantage on doing this conversion when running a supercharger? I may just be overlooking it. I see you get rid of the opti, which is great, and can take the engine up to higher rpms. Just trying to determine if it is worth going from a odb1 pcm to this.

 

Absolutely. You get the tunability of an LS1 PCM, and the reliability of the ignition system.
Going from an OBDII LT1 PCM to an LS1 PCM is like....going from MSDOS to Windows XP.

If you want to do this on an OBDI car, you'll need a 96-97 style timing cover with the crank sensor provision.

 

There are custom firmwares for the LS1 pcm that allow using a 2 or 3 bar MAP sensor so the computer can monitor boost.

 

The car is a 97. I did a OBD1 conversion on it before. You don't have to buy a new cover if your running a double timing chain?

 

You can run a 2 bar on an OBD I for boost..Thats the purpose for running a 2 bar. I did it back in 97 on my 95 and ran 14lbs...

 

My PCM doesn't have a "custom firmware" on it, and I have a FAST 3 bar map sensor on mine. works like a dream. Not sure what you're smokin'.

You need to have the 96-97 style timing cover to run the conversion. I assume you still have it on the car, considering it's a 97. You can run a double roller either by having your timing cover machined for clearance, or buy a billet piece from EFI Connection. Why do you need a double roller anyway? It's overkill.

 

Well I apologize, I remember people talking years ago about being able to load a modified operating system on the LS1 pcms using HPTuners or something like that to allow them to use 2 and 3 bar maps in order to more accurately monitor and tune for boost. I was under the impression that you could do it on an LT1 pcm but you would give up a lot of resolution on the tables. Sorry if I'm misinformed.

 

Im confused, How are you doing that without a custom OS? What boost levels are you running?

 

I have the conversion and I am running the custom OS 2 bar SD. qc97z I would like to compare specs with your tune and mine, primarily the VE table and spark table. PM me if your interested. Thanks Ben
