Oem V6 ignition curve/ map..does anyone have it?....

[Yoeddynz]

Hello there,

Both my wife and I have really gotten into this tuning thing and its really fun. So much better than mucking about with carburettor needles, springs etc.
We have started to get into the ignition tuning after having got our heads around the fuel side of things.

I am now not sure if we have retarded my ignition map to far. The car has certainly lost its 'Pep'- that really quick off the mark acceleration it had when the table in place (original one that came with the extra code) . We have been re-tuning the ve table to suit new ignition table in you're wondering.

It is easier to drive around town but I think I need to advance it back a bit. I have had a good look through the MS tables thread but most on there are not N/A and the tables are all different with some seeming very odd indeed.

What I would love to find is the original Mazda/ford stock ignition map. I would love to know what the maximum advance was and at what revs did it hit full advance. This would be really interesting information but having searched I cant find anything. Someone must have it somewhere? Currently running a KF right now.

I think I may also end up losing some economy with my new map.

This is my old map..



Here's the new map..



Cheers all,

Alex

There have been a couple of guys in the "KL" community who have been in the business of flashing new EEPROM's for our stock ECUs but I don't think either of them are still responding to requests from car owners anymore.

Do a search here, or on Probetalk or clubprotege for Stoker100 and/or Probinator. Either of those two guys woud have the information you're looking for if you can find them.

Here's stokers E mail, good luck. stoker100@hotmail.com

Cool. Thanks for that. I have just sent hin an email

I have the BIN files from Stoker from an email I got from him back in 2006.
Both ZE and american spec PGT.

Do you want me to host them? Maybe you'll be able to get information from them, maybe you won't.

yes please!

The problem with the OE bin files is that its all written in hexidecimal. You can see patterns of where the maps are located in the bin file, but its not like it's written out like in any sort of high level language, you can't just translate the bin into a MAP you'd see in tuning software, and you won't be able to determine what the spark advance values are.

Ryan is right. I've tried to deciper the tables in the bin files and they really don't make any sense. Even when it comes to the relation of the timing values across the table, it still doesn't make sense. There must be a lot of other calculations that go into it, and the tables shown are maybe limp mode only. I'll host them anyways, but don't expect to get much out of it.
I have no problem sharing my timing table that I used for many years with my Probe GT

Sorry I only just saw this; better to reply late than never!

Stoker100 and I figured it out using a dial back timing light. I'm currently mucking around with advancing timing on my stock ECU via an Eprom tuner. Definitely can say that the stock ignition timing is pretty safe and can be improved a fair bit.

Most people say that 27-29 degrees at WOT is the sweet spot from around 3K to redline. I am yet to test this with a dyno myself though. Looking at your map, the first table was too advanced at WOT, and new table too retarded at cruise speeds.

You can see that the advance on the stock ECU at lean cruise is much higher than both of your tables. That would be the general loss of pep IMO.
