How Does My Map Look? Mi On 45's, Megajolt, Petert Inlet...

[Stu 18]

Hi all,

 

Ive been playing with the ignition map on the 205, this is its current setup (i take no credit for it really, its a tweaked map i found on here based on one of Peter's i think? )

 

 

This one is one that got done by a supposed 'experienced' mapper, i was never happy with it so reverted to my own one.

 

 

What are your thoughts? Is my current map good? The fuelling is fine, this was the one thing that im happy to say the RR session did sort...

Why on earth does the advance go up with more load on the latter map

Top line (WOT) values look a bit fierce to me, likely only to need about 23-25 at 4-5000rpm

When I had my MJ bottom line was WOT, at least with the throttle down the tps showed 100 .

 

Anyway, don't know much about mapping but surely you can ditch the 8500 and 9500 bins and add more resolution lower down the revs.

If it's standard compression, as Sandy said, make the 100% line 25 deg. from 2500 onwards. The 90% line 26 deg., the 80% line 27 deg. and so on, up to 36 deg. for cruise. You should be pulling 34-36 deg. at light throttle, 60 to 100 km/h. I also agree with ditching the 8500 and 9500 columns. Is load sensing by throttle position? If so, I'd add more rows, say 3%, 7% and 15%

Thanks for the input guys, ive ammended the rpm and load bins, and structured the map as per Peters and Sandy's suggestions, not sure what to do with the lower RPM bins? Any input would be muchly appreciated, it currently looks like this:

why no zero throttle line? You'll be need ing that for idle and over-run
