    It is not the cable for sure, and it did read fine before tried to flash.
    Dropping xp will be a huge loss, so you might consider last stable version before you fully drop support.

    wow this thread moved fast. I skimmed thru a lot because I hate to just dive in a thread and ask a questiontthat doesn't make any sense lol but here goes.


    is there a link where I can look for the simple questions? like I'm guessing this is for a software you wrote to be used instead of tuner pro. scan and flash all thur the aldl. is there a under dash ecm this will run in? being 94-95 z28.im guessingtthis is Sequential injectors? what kinda cam sensor signal does it need?

    have some ideas for a Gen 1 using Northstar coil pack mod. it will send out a 1x cam sensor pretty easy.

    Yes, it is sequential. The cam signal is from an Optispark which is unique to the Gen II LT1/LT4/L99 engines. To me, it appears you could put an Optispark onto the front of a roller-cam Gen 1 small-block by swapping all the associated parts over, but I have never tried it and can't confirm it.

    i've often wondered how hard it would be to rip the optispark code out and replace it with the input from a normal ICM or cam reluctor or whatever. the special nature of the opti signal is really the only thing holding this ecm back from being used on alternative engines.

    oh, yeah, try the new beta. it seems to work better with win xp. i dropped 64 bit support, it was unnecessary, changed compilers, and rebuild QT entirely with different flags.

    one initial observation of testing the new builds is that memory usage is initially higher, but during logging, MUCH lower. this is good news.

    visual c++ does some bullshit memory pre-allocation optimization that didn't seem to work well with my arbitrary 'dump a ton of random data onto the heap' design, and would exhaust memory, but the gcc-based compiler seems to act normally.

    you're right never realized there was a inner part of the wheel for the cam location and the other.


    yeah, thst totally won't work then. shame ccause it would have been nice.

    yup! if you hacked up an opti and made a cam sensor it could probably happen, though

    yeah you'd have to put the rotor and optical pickup in a dizzy and then run the n* coil packs. or something. and then the dizzy runs half speed of the cam if I'm thinking of that right?


    we did this once to a 93 lt1, to delete the opti all together and run a older ecm

    http://lukeskaff.com/projects/car/ca...c-ecm-project/



    for a min I was thinking, hey. I could do the n* and run a simple 1x cam sensor in the dizzy and the 94-95 ecm would work. but nope. I see now it's a very special cam signal input that is different for each slot. how are the v6 guys running it?

    so a lt1 pickup inside a large cap hei and some kinda opti coil pack swap box from msd, is the only way I'm thinking it would work. which would be nice, but over my head money wise

    anyways. keep up the good work. it's fun to follow along the thread just to see the process.

    I've actually seen some pictures of where a guy moved the opti to the traditional distributor location. He was a machinist though and made the parts he needed to make it work. I don't mind the opti or the limitations of the lt1 pcm, as they don't really effect me at my mod and power level, but to get it from under the water pump would be nice.

    i have no decent experience tuning automatic transmissions in $EE.

    i want to fix up the automatic transmission section of EEX as well as provide some good baseline transmission tables in my free online tuning service thing.

    can someone teach me (and anyone else who reads this thread) the basics?

    is there a decent formula for what to change with a higher stall converter?

    how about eliminating 'stall wall'?

    what's a good rule of thumb for baselining line pressure?

    does anyone have some properly tuned auto trans bins i could reference as a learning tool?

    Well it turn out to be bad adapter. 4.10 writes fine, with other adapters I tested.
    So the question is what happened with this adapter. Last time I used it, was ok.
    I will test latest beta later. I ran out of good chips, have to do some programming.

    Auto trans table are almost defined, but needs more work especially the pressure tables and adapt tables.
    I have compared the main pressure tables and there is different approach across bins. So it will take more time to be able to help.

    glad you found the problem and that the problem wasn't me ...

    hey i'd really like you to try the new beta since i don't have many xp users, i think it'll run way better, please also review my definition file, you understand the datastream so i'd love it if you'd review my parameters. also please reccommend other parameters for my E-side message and see if you can provide any info on unit conversion or whatever.
