EFI ignition maps

[jonfriedline]

Thanks, I found some of these as a starting point so much appreciated. I have an 86 930 that I'm trying a haltech e6k to start playing with.

Here is my initial ignition map.
Stock 3.0CIS engine but with 9.5:1 compression. Stock SC Cams. Single plug.
Stock headers with J Pipe. Turbo is a Pulsar 3076 0.63a/r. EFI using 3.2 manifolds and Ecumaster Emu Black.
Wastegate is Tial F46P with 0.5 Bar Spring
Engine starts and runs well. Drives OK but I have been very gentle and not seeing boost often.
Would appreciate some pointers on where to go from here (yes, a dyno and pro tune is on the cards)

That is a really good link and editorial and there are more good ones down at the bottom of the page.

@mikedesilva thanks for sharing your map. One q - I see you’ve got the timing increasing right up to 7250. Some level off the advance or even taper it a bit. Curious to know your thinking in doing it that way.

Was purely an entry level map given to me to get me running on the test stand and also for the car to be drivable before going to a tuner. There doesn't seem to be many people who have efi on their cars that are reading this sadly

[mikedsilva]

Any other takers willing to share ignition tables?

In particular, Im trying to understand where to advance in order to increase spool up earlier in the rpm range...

3.0SC engine with 3.1 kit (9.7 Max Moritz pistons, SC cam, 3.2 manifolds, aftermarket ecu,COP, std heatexchangers with J pipe, Pulsar 3076R,no intercooler yet!

Here's my updated map. Purely from looking at stock ignition tables and running on the street. Car is driving well and has not been to a dyno yet but would appreciate some input.

May be a quiet forum subsection, but sharing these along updating them will be a big help for others. I know I'll be referencing here when I get around to my efi+turbo SC project.

I am going to be starting to work on this too soon.

Using a Haltech Elite 750.

Retarding the ignition on tip in should speed up spool, unfortunately I have not gotten to the tuning portion of my engine, so I have no map to share.

Retarding?
Interesting... might give it a go.
With the number of people running converted turbos that used this forum for their guide, I'm sure there are a bunch of lurkers that could share there maps!

Here is mine but why do you think my advance number is higher than specified? I do have mat and oil temp adjustment but at the temp at the time it should have been out of the equation. Thoughts?

Who pays attention to egt?

[jpilcher]

Here is my Megasquirt Pro Ignition Map.
Idles well, 1st is very short, pulls strong through 2nd, 3rd and 4th. Would like to play with retarding timing to spool earlier. Thoughts on where to adjust my map. Engine is Twin plugged.

Thanks

John

Interesting. Who wants to show the afr table as well?

This is me..

maybe Im too conservative?
