Is the stock table available for SPI or MPI?
Is it published somewhere?
This is my timing table data size.

Getting ready to start my ECU programming and I am looking for the timing advance table or at least some data points so I can build my own table.
Is the stock table available for SPI or MPI?

I'm not sure if it's any help but I have an aldon yellow set to 33degrees BTDC at 3500 rpm no load vac disconnected.
I can get you a MAP reading at that figure on Sat if you want.

actually contact the megajolt website too as i know there are folk on there that have setup minis, didnt realise it was jsut timing you were after!!
i think its somethingk like http://picasso.org/mjlj but dont quote me!

Thanks for the suggestions so far.
I was able to locate the specs for the 123 distr curves so the data points listed will allow me to plot a couple curves.
I would still like to see the actual curves or tables for the stock SPI/MPI.
Here's the 123 specs

Nobody knows what the standard ones are, id be interested too, but i do know that my spi idles with around 15 degrees and foot flat acceleration is 37 degrees. The last was causing pinking on an engine with CR of 10.5:1 and RON 95 UL.
As a matter of course, i will be trying to extract as much information from my standard ECU by driving while monitoring, so to build a rough map to start with for the VEMS.
I'll keep you posted

Thanks,
I just used the 123 data and built up 3 different tables I'll post the avg table in the build thread for you to look at.
