Coming from a guy who can design and build an electronic device!!

Gotta love it!

You have to first upload the photo to rennlist. Then you go to the "go advanced" tab, and insert the picture as the filename you uploaded.

An accurate statement for you to make would have been "But there is no way to re-map the LH, until John is done with his work... that I'm aware of."

A couple of S4 emulator mapping screen shots for the LH:




Since the fuel injection and ignition are controlled by the separate LH and EZK, the emulator has to be used with one at a time. In other words, the emulator gets connected to the LH alone to remap fuel, and it gets connected to the EZK alone to remap ignition.

Nice work Z !

Or I could have said "But there is no commercially available way to re-map the LH, until John has done his work".

Come on John, hurry up man!

Um,

This is slightly incorrect. This can be done in week with an army of Software Engineers and a boat load of $$$ The issue is the amount of resources and time to get this done in an economically feasible manner...

Having been involved in several technology ventures, this little LH and EZK code is not much to crack... Time to do it, technically proficient people, and the $$$..

Emphasis on the $$$.. I have some colleagues in India that would make this look like a walk in the park....

Now, having said that, I do not wish to pay a king's ransom either..

So, John, we are all waiting on your gallant efforts so we can explore the outer limits of our engines......!

John Speake

It's not only a question of re-mapping. This is OK for mildly modified engines. But the s/c engines need more undersatnding of the limits of the electronic hardware and software for the 928.

This was mentioned earlier in this thread.

The hardware is finished, work is proceeding on the software. But I'm not a software expert, I leave that to more capable people...

Um....Untill it has been done then the statement is completely correct. Virtually anything can be done. But until it is done, it's proof does not exist.

True, but then you will need an army of real users to debug their work for 6 months or longer...

Dave,

Not true.. Some colleaues of mine have written software tools to do automated debugging.. The LH and EZK do not have that many variables in their input/output function...

The sensor inputs are well known, and the output signal is a function of load... Not that difficult.. A good Software engineering team can do this in very little time.. The hard part would be cracking the code to see if the boxes use embedded versus Eprom codes... My guess is that the majority of the information is on the EPROM... Back in the 80's things were not as sophisticated as today...

Believe me... This is not difficult when compared to the guidance system of a missile....!

Don't ask me how I know. You will have to take my word for it.

Obviously it has been a pretty cold winter.

Richard,
>Not true.. Some colleaues of mine have written software tools to do automated debugging..

It was a spoof at most of the software being written, not neccasarily simple little "math programs". No matter how good it is you never know where the bugs are until it it truly used by many users who travel thru all of the almost infinitely possible "threads". If your friends truly have an automated software that will debug any software perfectly I suggest they contact Microsoft ... and then decide what country they want to buy and retire in. PLEASE ask them to sell you and I a small share before they call!!

We are talking here of a system with a very small potential market. I am sure an expert team could do the work in a very short time. But at what cost ?

I hate to think how many hours it took me to get the Spanner software sorted out. But there is no way I will ever recover the cost for my time. It has been an interesting project though !

DR

Hi John,

Certainly not at a cost that you would be able to sell it to the small 928 market, keep up your great work just the way you are doing it!

If you bring in a pile of "experts" then probably none of us will be able to afford the cool stuff you are creating.

BTW, everything is a go as per our discussion earlier, I am excited about it and look forward to it!
