    411 vs E40 PCM?

    I'm trying to decide between using the 1kb version of the 411 PCM and the E40 PCM for my swap project. I currently do not have any PCM/harness, so I will be buying parts regardless of which way I go.

    Which is the better performing system? I like the idea of having everything in one with the E40, but I have only ever worked with the 411.

    I am using a 24x LS6.


    Advice?

    I prefer the E40 personally. E40 will require you to use an electronic throttle, but BFD. It's a little faster and has better functionality IMO.

    What makes the E40 better? I'm going with DBW either way so that's fine with me.

    I like the way it controls idle better. It also has a faster data rate.

    So as I understand it, the e40 (with the 24x) was 2005 and 2006 only?

    I'm pretty sure I've got a couple of them. I'll check today.

    A buddy of mine has a GTO PCM and harness that he might sell. You'd need a 05-06 GTO gas pedal.

    IMO I hate using parts that were only available for a few years. Not only is the E40 harder to come by, but it's more expensive when found - ie wrecking yards.

    I'd stick to the LS1 truck PCM's if it were me. Or upgrade the reluctor and run an E38.

    I was under the impression that the E38 was still not fully supported/easy to tune and needed Tech2 flashing before it could be tuned. Is this not so?

    Don't know about all of that. I've never had an issue. I have a Tech2, but I've never seen it be required.

    But if not a E38, what about an E67?

    Keep in mind I'm also trying to keep you away from a special one off pedals and etc, too. E67 should run any car pedal. Not 100% on truck? I think all trucks used the E38 and cars used the E67, because it has more IO ports, I believe. Typically the car and truck pedal can be swapped around with minor wiring mods. So that may not be a bad deal, just research it first.

    I do a lot of conversions and mad-hatter deals - ie multiple year modules/VIN's in one rig that shouldn't work, but it does when I'm done. I like truck components better, because there are so many of them out there. They are cheaper and easier to find.

    If you used one of the 58x computers, you could get a crank out of a 58x (07 new body and up) 5.3l or 6.0l. Just have the complete rotating assembly balanced before putting it into your LS6, as I think the bob weight will be different....

    Is there any real gain to the 1mb PCMs over the 512kb PCMs? The older 512kb stuff is dirt cheap and plentiful.

    Maybe someone else will know more, but I believe them to be faster and capable of higher resolution fueling/spark/etc.

    Question would be "does it really make a difference"? Nobody seems to have any issue making ridiculous HP from the "old" 512kb PCMs so it would be nice to know if there actually is a performance related gain, or if this increase in memory was somehow related to emissions/diagnostics.

    E38's are completely tuneable in a standalone deal... I did a LS3/L92 in a 240sx not long ago that was still running the stock 2007 escalade operating system. Once I had all the junk that obviously was no longer there turned off it did fine.

    I'm actually thinking about switching to an E38 myself so that I can take advantage of larger MAF tables, boost cut, faster processing, individual cylinder timing and individual cylinder fueling (not tried it yet but waiting for a test car to use as a guinee pig).

    Any difference between the truck and car e38 PCM? I will be using a Vette LS2 90mm TB on my project.

    As far as I know, no. However, there are differences between years. You can't put 09 VIN in an 07 PCM, for example. I learned the hardway, and bricked a couple of them. After flashing them with incorrect year (via Tech2), the check engine light will flash. If this happens, don't shut it off. flash in the correct VIN, then shut it off for 20-30 seconds, and turn the key back on will save it.


    In fact, there have been times I needed PCM's for a certain truck, and the local yard gave me one from an Impala, or etc. So no, I don't believe there are any car vs truck differences....

    I cannot comment on the differences per year but usually the controllers are all very similar for a particular year. I would get as new of one as you can get as the 06-07 OS's are finiky. I would also probably get the matching TB for the year ECM you get as well because some of those TB's act up a little between years. So 08+LS3 tb for 08+ ECM and LS2 TB for 06-07 E38's.
