std ignition map

Think i remember Scoff having numbers for the ignition timing at certain loads on the std Remix unit? Anyone still got these?

Also does the remix unit only adjust timing due to load or does it use rpm too?

with thanks

This is the base map I work from when tuning a C1J. I did it a few years back based on the timing I pulled from an RE209. I say base because ofcourse every different engine build will want a different map. this will get you going.

Thanks Scoff :)

I used the map from scoff also:agree:

This is my Ign map for Emma car on megasquirt, i have not changed it much but i would stick with scoff as lpg is 114ron;):D......i should re-map the ignition to try and get more out it:coffee:

Looking at that map you have alot of room for ign miller spec on 107... (it is hard to see tho to make out) is that total timing on 20 at 1bar? do i need glasses or what?:)

hold control and + / - to zoom in and out.

Just out of interest whats the kpa (kilopascals?) with reference to on that map? and is that degrees of advance?

100 = 0 psi
200 = 14.7 psi

and yes:)

KPA is pressure

0ka = - 1 bar
100kpa = 0
200kpa = 1 bar and so on

So to state the obvious more boost = less advance? how is that calculated?

Edit: How rude I didnt even say thank you! thanks for the response ;)

I see what you mean, it is less than the standard map that i got from scoff........i must have fat fingered it when transferring it to megasquirt:D

When i remap the car in a few weeks i think i will put it up to standard numbers for just now:ashamed:

Dont forget to take in consideration what turbo/cam and boost you run for correct ign around peak torq. guess on 107oct and stock map be fine anyway..

isnt there more fields to the grid on mega?

What fields do you mean?

Sorry i see what you are on about now

I have MS 1 Extra with the V3 board and fuel and ignition are both 12x12.

I can upgrade to MS 2 on this same board, all i need to do is add a £100 daughter card and i can have 16x16 maps plus a few extra features:)

Both ecus allow you to move the rpm and map point to where ever you want, they have full interpolation between points.
