MJ Map Question
Turbo Mini Forums

had the mini set up the last month on the RR but dont understand why the map has been blocked out at 32 degrees on vacuum, when all the other maps i have seen dont.

My Map:


mini runs really well and produced 106 bhp on a n/a

Does look a bit odd. I don't know why the RR would fix the advance to 32 above 4500 RPM? Who's rolling road did you use and could you give them a call and see what they say?

Saying that 106 is a good power output, Is that's definitely the map currently flashed to the MJ?

theres a simple reason for this,

they either don't have a clue what they're doing, or cant be arsed to do a proper map!

basically they have run it up to peak, played with the timing there to get peak power and though fuck it that'll do, exactly the same as if it had a dizzy.....

what they should do is hold the speed at each load point and adjust the timing to suit.

thats is the map out of the MJ, the map was playied around with at lower revs as there was a lot of chocking around the 2000 to 3000 mark.
it was set up at minisport, the mini does run fine and produced good power and torque for a n/a 1330.



new to MJ so was unsure on what was really going on, only really noticed when i got home and compared to other maps.

may look in to getting it fettled but where is a good RR as from bolton (Lancashire ) go on i've let myself in for it now (whippets and flat caps posts)

It seems that the RR guy has done probably what he was paid to do. Get maximum power and a car that runs well.

As you say he messed around with the lower end, which will make the biggest differance to driveability. If it drives well he has done a good job.

What he hasn't done is whack in a load of advance for the cruise section of the map (part throttle, vacuum mid rpm).

To be fair, most of the 32s are in a bit of the map that will never be used. I'd be tempted to go for a drive and see what bins you are in at cruise and stick in a load of advance.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

I would expect to see a heap more advance at cruise,

at 3-4000k and 60-80kpa I'd expect more like 30 degrees advance or more,

i'm very reluctant to alter anything after blowinga head gasket after 5 miles before the RR.
please with running straight cuts and a 45 its quite hard to listen for pinking arounf the 3-4k mark.
but you have got me wondering now, will have to plug the laptop in the next time im out and have a run around and see what load bins are used for normal driving.

should i lso be looking at adding more advance on deceleration 10-50kpa as per the map below

advance could be added on deceleration, but its not going to be a big issue unless you are getting any popping form the exhaust on over run.

no popping at the moment :(

will prob look at adding a little advance around the 3-4k and see if anything feels or sounds different.

normally sit on the motorway between 3 1/2 - 4k.

hell of a lot of losses on that dyno ?

joe i think that when lee says decceleration he really means the cruise area sort of fing .

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

ahhhhh....

by deceleration I understand anything less than about 35-40kpa

deceleration may have been a bad terminology on my part.

i should of said below 40kpa, i think it would be a good idea to have a drive around sensible and see what bins are used.

probably look at changing the 4k column to may by 28-30 for 60-110kpa, if that sounds right and see how it runs and sounds.

thanks for the advice guys

yep deffo have a drive round and a look at the cells, even if its just to get an idea of whats going on.

will do that, thanks for the advice joe.

keep you informed on what i find, could i also find this information out off the data logger?

going to give the mini a run with a slightly revised map.



added some advance on over run as per all maps i have seen and added a little on the 4k mark across the board.

I like extra fuel and 0 deg advance on overrun :)

Yes i moved to the darkside

would that introduce popping and flames

lol

yes, extra fuel and a late spark is basically the idea of antilag.

cool, that extra mid range advance should get you a few more MPG's, you might be able to get a few more degree's in there, but it's dependant on engine spec, I think Ive run about 37-38 deg in that range before, but thats on a turbo motor with lower compression ratio.

was thinking of stepping it 30 but lappy went flat (school boy error) motor has quite high compression as pistons are 10:1 but benross has built the head with different chamber size so may be a little less.

seems to run fine though with no keys jangling :) thanks for the advice joe / brett

may add another degree on the 90-100 kpa from 5.5k to 7.5k and see how its feels

dont go mad with it at 90-100k as thats were the det can get you, and to be honest you probably wont feel the
difference if there is one.

thats probably what happened on first outing as had about 35 in up there so on your advice i'll leave it at 32.

tbh i'll prob leave map as it is now, as mini seems to run sweet, and checked all plugs and all is looking good.

Hi lee, looks like you are on the right track, and i agree with your slowly but surely style. To all, my understanding is that MJ has the facility to self improve over time- particularly in the cruise sections? - like an optimise function?

No mj cannot self learn it can only do what you tell it to

Yes i moved to the darkside

Instagram @jdm_brett

yep thats true as on the first outting my right foot told mj to blow my head gasket.
its was a quick learning curve but seem to be understanding it a little now with the help of tm members.

may look at changing the 28's to 30's and 30's to 32's on next outting and see how it feels.
but very happy with it at the moment.
