Chips in a OBDII PCM?

[Lextech]

I have the Moates LS1b RoadRunner PCM but, haven't used it yet. I have been told that you can flash it with a 512kb (99-02) or a 1mb (03-07) calibration. My truck is put away for the winter but, I hope to play around with the RR this summer.

I've got a RR sitting here as well waiting to install in my vortec truck thanks to your work on the conversion!

But I've actually broke some new ground with the 98-00 vortec PCM on EFI Live forum and have the Calc VE Calc MAF and almost the AutuTune tutorials working for the Vortec. One piece of info has been missing the whole time to make it work, it's the commanded AFR! It's named wrong in the Scan Tool so no one has been able to make it work. Right now we have a request in for MORE PAREMTERS, which are there, just not installed by EFI Live. Right now I'm using a cross of EFI Live, TunerCat and Hex from the Disasembly and it all works!

Once it's done the Road Runner is going in!

About this theme,I think I will give you a suggestion and offer you some information on Chip Tuning Tools .Them will be useful!

Hardware looks applicable, but hardware alone is not a complete package for OBD II Tuning! Any OBD II data logging software available?

Thanks for the in depth info 1project2many. This puts it all into perspective!

The idea of doing that and using the AutoProm or other emulator is intriging...

[RobertISaar]

not that i've opened one to find out, but i THINK the largest BIN the autoPROM will deal with is 64KB.

[EagleMark]

Well I just tried to Upload a 512k bin to AutoProm and it says I messed up?

[EagleMark]

Need bigger chip?

[RobertISaar]

that's a 128KB NVRAM module.... explains why a 512KB BIN would be an issue.

I'd like some feedback on what could be a practical path forward for swapping the flash chip inside the LS 0411 PCM. I know Mark is interested in having the flash chip outside the LS 0411 PCM, but I interested in having a ZIF socket mounted inside the PCM for the flash chip.

I don't have much information about the internal electronics of the LS 0411 so I'm going to ask for some help here.

Is the LS 0411 flash chip available from electronics suppliers like DigiKey or Mouser Electronics? I'm thinking DigiKey and Mouser have the ZIF sockets available.

I'm thinking the binary file from the LS 0411 flash chip could be read and edited with software (TunerCats) used by the RoadRunner?

The idea I'm getting at is modify the LS 0411 PCM with a ZIF socket for the flash chip. Then read and rewrite the flash chip and install into the ZIF socket.

I see many practical applications for a LS 0411 PCM that has a ZIF for the flash chip.

the flash PROM is a fairly common Intel unit(AB28F400B). supposedly, at some point in time AMD units were used and they are 1MB instead of 512KB(AT28F800B)
