Default EFI connection guys!! RPM limit on your setup

What rpm are you guys spinning your engine to? What are your setups and do you like your ltx pcm or lsx pcm better?

Aside from Cranberry and S10Wildside, I don't know of many who actually have their 24xs dialed in yet.
FWIW, my limiter is set at 8000 at the moment.
We'll adjust that once we finish the dyno tune and set shift points.

Having tuning experience with both PCMs (more with LSx), I can say the LSx is like bareback sex while the LTx computer is like wearing 2 rubbers. A standalone ECM is comparatively dryholing Jessica Alba.

I had the stock 93 LT1 ECM before this, it can be made to work but just like the LT1 PCM of later years but it was next to impossible to find any one local willing to mess with it. I didn't have any optis problems so that wasn't a plus or a minus either way. The EFI 24X was chosen because it uses GM parts, the harness was like factory and I can use soft ware like HPtuners to tune the car. Unfortunatley it never got tuned, work got in the way and it's been sitting a lot. Going back to do Kooks Long Tubes and a new Y pipe, after that it'll get tuned. The car has a stock short block, Dart Pro-1 Heads ported by L.M.E and an off the shelf CC306 cam. Not sure what it'll spin to, what ever it makes power too, I could care less for hurting the stock short block.

Mine's nicely dialed in...
IIRC, My limiter is currently set to 7500.

I'm loving the setup. Not only is it much more tuner-friendly, it's cleanly put together by the guys at EFI Connection, it's well-designed, robust, and dependable.
To me, it really converts the ignition system to something much less complicated. With individual coils, it wouldn't be too hard to diagnose a cylinder misfire. No more high/low res codes, no more opti ghost issues to chase.
Go for it, and don't look back.

IM just seeing what others are doing for their own setups. IM seeing a lot of people wanting to convert. So im just wondering what RPM limits all of the ltx guys are going to. Also what cam specs these guys are using.

Initially set rev limiter to 7k, but intend on moving to 7.4k.

246/254 HR cam. Great system, happy I did it.

Cam specs don't make any difference with this setup. Choose the right cam for your motor.
Mine's an LE custom blower cam 219/230 .585/.585 114 LSA.

spinning a HR past 7000 and MAKING POWER will take some good parts.

The RPM range for the motor has a HUGE effect on what kind of cam it wants, so yes the cam specs will change for a 6500 power peak and a 7000 power peak.

EXACTLY why im asking about the cam specs and how they are effected by the RPM especially while using the lsx pcm. I want to see what cams people are using and what RPM they are taking the ltx block to on a HR cam with 5/16" pushrods, ls7 lifters and pro mags.

ditch those lifters and pushrods. how much do you want to spend on springs and what kind of installed height do you have to work with?
