Please explain the resolution comment..and what is that supposedly affecting.

I'm not a tuner, I admittedly don't know all the fine details about it. I was just trying to point out that these features were available in the LS1 pcm and that they are supposed to offer advantages for tuning boosted motors. Maybe the extended/added tables aren't beneficial, I don't know, it's been years since I researched into PCM options for a boosted setup and I remember everyone being pretty excited when that stuff came out for the LS1 pcm. I have a rudimentary understanding of the resolution of the tables on a stock LT1 pcm from a customer's standpoint, but not enough to warrant trying to explain it as it relates to real-world tuning and if it offers any tangible limitations/benefits.

 

I wasn't trying to say i need it. It currently uses a double roller but it's not a huge deal to me to change to a single roller. Main thing here was for me to try and see what advantages this conversion provided and to see if it was worth the cost.

 

You get rid of the opti and potentially temperamental ignition system, a PCM with more tuning capability, and greater tuning support via popular software suites. The cost of the system is not for everyone and not every car needs it. For my use, it's just what I wanted and has been working flawlessly so far. Being able to log and work with Hptuners just makes my life easier. This is coming from someone who never an opti related ignition system issue.

 

My LT1 wont run untill I get this conversion. The only things that suck about an LT1 is the opti and trying to find a local tuner. Its a bit of an investment but better in the long run IMO

 

Thanks for the replies all. I appreciate the feedback. Now I have some thinking to do to determine if this system is for me. I have never had any opti issue and have the programming tools for my OBD1. So just need to determine if this is something that will benefit me.

 

The conversion is definitely a step up. But I see a lot of people going to this system just because they truly do not understand or "Think" they need it. If you can afford it, Great. But everyone keeps saying better tune ability. If you know how to tune then it really doesn't matter what OS you use. I agree the Opti Crap is our main dilemma. I would still like to see someone that had a OBD I set up and WITH no other changes only the conversion and see if they really gained any HP. If your setup is making power past the 7200 RPM mark then Yes the X conversion will benefit you. But I see mild builds that will probably peak at around 6200 or so and people telling them they need to switch to the X conversion to make more power, Not so. Mine is forced inducted, OBD I and made 722 RWHP at app 6000 RPM's. If I switch to the X conversion, will I make more power? I don't think so....

 

I don't know what other people are referring to, but when I say better tunability, I mean there are many more LSX tuners out there than LTX. It's easier to find a local tuner, and every tuner I talk to mentions the LSX platform is easier to tune than LTX. The LSX pcm is more advanced...plain and simple.

 

Based on the feedback I have been receiving from a few dyno tuners, and especially because your engine is forced induction, you will see an increase in both power and torque. I have asked the "why?" question and they all believe it has to do with ignition accuracy (with the LS1 PCM). However, I don't think that increase is necessarily worth the costs involved to use the LS1 PCM. But that's just me...722 RWHP is unusable on the street anyway, so why make more power?

 

ON your quote, I agree, More local tuners. The LSX PCM is more advanced, OK, But what do you get out of it. Like I said I am still waiting to see someone with a setup and like I said with no other changes other than the conversion, How much did they gain...





This could be true with the better ignition, with the coil on plug setup but again like I stated above. 722 RWHP unusable on the street?? If you saw my car you would of thought it was a bone stock Z. I drove that car daily, on 400 mile round trip "With AC" Yes you need stickies to hook on the street, but other than that You would of loved the looks on the faces of the people driving Z06's and Vipers on the highway when I just pulled away

Bottom line, like I said, I see people with mild builds and others telling them they "Need" the conversion when that is not a true statement...

 

My car is a street car with A/C...and I could always use more power

I don't NEED to drink beer every day. I don't NEED to even own a car.

I did the conversion because it makes things easier and less complicated, and more dependable. I didn't NEED to. I WANTED to, and benefit and peace of mind was had from doing so.

 

You are missing the whole point, which I knew this would turn into. You "WANTED" to do the swap, Good for you. One is asking about the conversion if he "NEEDED" to do it or could his set up run with the stock PCM. He is asking a simple question, People on forums give bad advice for others that are not as knowledgeable as some, or just chime in to add derogatory comments. I think he got his answer.

I am doing just this conversion next month nothing else added but the conversion I will let u know the results once its installed and tuned later next month

 

It really gets back down "to each his own" saying. If you have the money to spend for the conversion even if your set up does not need one and it's what you want and are happy, hey, more power to you. I, too agree that if your set up does not require to spin over 7000-7200 rpms to make power, then I would spend the money elsewhere. My reason for doing this conversion is for the plans I have for the next engine upgrade, which I know will require to spin past 7000 rpm, or to the moon. And if you look at the date on the start of this thread, you know I've been thinking about it that long and just now and finally doing it. I will also update with pics/vid as time progresses.

 

^^ Exactly.....

 

Moe, I know you know your ****. I wish you were local.

 

Thanks for the feedback. I see my question was finally understood. I think i did get my answer.

 

Ok, sorry to bring a thread back from the dead but I have a question and want to be sure. Lets say that I find a car for sale thats had this conversion but the motor is blown....can I pull out the LT1 and put in an LS motor without any problems wiring harness wise?

 

Negative. The Efi 24X conversion wiring harness was made for an LT1 motor utilizing an LS pcm. You will need an LS wiring harness for an LS motor. Hope this help you out.

 

ok, thanks for that clarification.
