Megajolt map, can someone check it for me?
Turbo Mini Forums

Hey all

Finally got my laptop to speak to the british open classic by going back to one of the early software revisions, heres the map, ive had a look at a few others that have been posted mainly for turbos and bigger engines and they seem to be advaced a lot more at low revs?
the car seems to run and drive well and i think the flat spot is caused by a worn carb which im changing this week.

Engine spec 1275cc MG Metro -standard internals, running an MPI rad setup and a HIF44 with BDL needle i think and a K&N cone filter so pretty standard allround.

Any modifications and reccomendations greatly appreciated!

I think most people run more advance to help with off boost driving.

Mine generally idles at 15-16 degrees. It may also be worth putting a higher value in the 500/10 box to help prevent the engine from stalling if it drops that low.

1/4mile in 13.2sec @ 111 terminal on 15psi

that looks reasonable for a NA engine,

you can probably advance it more around the cruise area, 50,60,70 kpa 2000-4000 rpm. try to eek it up to 35 degrees at 3000/70 kpa a little at a time keeping an ear for pinking, if it pinks pull 2 deg out at that point... keep the changes cell to cell smooth, and add timing to the whole first row to stabalize idle, try 15 deg in the 500rpm row.

thanks for the advice lads, will get the new carb fitted and tune it up on the weekend.

found this map on the autosport labs site, its seemingly for an spi with a 286 cam should i be aiming more towards this?
