hi

it could be interesting to open a post where all mini owners who fit a megajolt kit will publish maps of their set up and a short sum up of their specs engine. I found one web site where it is possible to find 5 or 6 maps ... i think we can do much better on the mini forum.

really what is this website, I could only find a few on the megajolt site, hope to get mine done on rr in the next week, i will put mine on.

need to sign up before to downloas. Suppose you got the megajolt log. Easy to find on the web. Google is your friend.... for ever... lol

Most of those maps are on the megajolt website.

not sure I want to sign up to too many sites as my spam filter is filling up with record numbers of S***E lately.

Once mine is up and running I will put a map up. Is there anybody out there with good general advice on how to map, at the moment I am just stabbing in the dark and using other peoples maps.

After a bit of tweaking i got my 998 Stg1 with a HIF38 carb to run very, VERY well on the 998 Stg1 map on autosport labs website.

correct way is dyno tune.

problem with megajolt is the sensor is very rarely positioned spot on, so that error is added (or subtracted) from the figures on the map.
So after downloading a map close to your engine spec, try reposioning the sensor or trigger wheel (as if doing the timing on a dizzy), I ended up advancing mine some 15degs and it run a lot better.

not enough advance and the car will be slow and prob burn out the exhaust valves.

too much advance it will not start properly (turn over very slow) and probably det and melt your pistons.

Was getting all excited about getting a megajolt set up, but this worries me now .

Though that's true, you can still use the advance curves as an example map and adjust where the advance starts.

Matt just want to say your Megajolt guide is awesome, thanks for doing it, your a true TMF legend.

[Tomf]

Matt your a true legend.

Seconded. Top Top bloke

You know its true .

The risks of bad ignition timing are no different with MJ to any other system. You can still use a strobe to check the accuracy of the mechanical parts and V4 of MJ allows you to advance or retard the whole map easily, you could still do the same with V3 by editing each cell.

O right, so you can check if your ignition is ok by using a timing light?

Only asking this out of curiosity but I noticed a few of the posters mention 998's

Does the MJ give much of an improvement on a 998 ?? just seems a lot of trouble and depending where the parts are sourced from expense. Can see where it could be usefull on bored out 1275's , just the 998's I wonder about.

I'm in the dark where MJ is concerned so just improving my knowledge
