timing map on M30 anyone willing to share

[scoobydo]

All having my M30 engined E30 mapped on Saturday. It is boosted and was last mapped in 1996 but turns out that it was still on 1986 fuel filter. All service items done running ngk 7s. Can anyone give me a copy of there timing just purely for reference purposes? Car back in 96 was 450/520

thanks a lot

Read through the Megasquirt FAQ thread and there are several timing and fuel maps posed.

Here is one of my older timing maps from that thread. It's tuned to 14 psi on 93 octane ((RON+MON)/2). This is on a 9:1 b35. I've since tweaked the light load cruise a bit, but it should get you close.

ok fantastic, we get 99 Ron here, car has had its compression lowered to 6.8:1 but intercooler position leaves a lot to be desired so intake temps will need to be monitored very closely running 20psi. Eventually will be altering to front mount but that means pushing the engine back a bit as the rad sits in the aperture at the front rather than across the front slam panel so takes up a bit of room where the front mount will go.

Is 6.8 even possible?

[Brad D.]

That is possibly the lowest compression ratio on any turbo car I know of. I can't image it does the car any favors. 20 psi is doable with much higher CR than that.

How was that CR achieved and why so low?

[scoobydo]

Unfortunately don't know what was done and why so low. All the Turbo work was done in late 80s early 90s. Everything was blueprinted and reassembled there are bills for 1000s.Strange thing is even with this low CR it still gives 12psi vacuum at 750 rpm compression test gives 150psi maybe someone calculated it wrong

[GI jonas]

Forget that the 6 is in the ratio. Now it seems legit.

Brad D.

Are the loads sites in Kpa? So anything above 100 is not actually relevant.

Thanks

Load sites are in kPa absolute. Why would it not be relevant? Everything below 100 is below atmo and everything above is boosted. Like I said, that map is tuned to 12 psi (~182kPa) on my car.

[scoobydo]

Opps wasn't allowing for atmospheric pressure so makes perfect sense now.

Tks

Here is an acceleration run on the road with 2 passengers from 20mph in 4th gear to 120mph. Boost was 18psi ambient temp 21c
