Megajolt Map for 4.6 Comp Safari LR

Recommended Posts

Hi,

 

New to this forum.

 

I have just fitted a Mega jolt system to my LR Rover V8 with 4.6 bottom end and 3.9 14 CUX top end.

 

I have searched the internet and this forum for hours looking for a good Ign Map.  I can find lots for 3.9, 3.5 etc but nothing for a 4.6.  Everything I read says that a 4.6 should not have as much advance as a 3.9 etc.

 

Does anybody have a good map as a starter for 10?

 

Thanks,

 

Michael

Right, here's my (Megasquirt) MSQ's plus a screenshot just in case...

The 109 (4.6 V8, piper stump-puller cam):

The 127 (Stock 4.6 V8, GEMS type):

You should note that although I can solder 'em together I'm a muppet at tuning, these have been set up by more knowledgeable types and I've made minor tweaks where I've felt the need - so don't take these as a masterpiece of performance tuning - there's likely a lot that could be improved!

Also bear in mind your timing marks have to be right in the first place ;)

Hi Fridge,

Thanks very much for the maps.

Is the left axis in KPA?

Which one would you recomend I start with? 3.9 14 cux top end and used for racing?

Are the map colours significant? Just wondering what they mean if anything?

Regards,

Michael

Screenshots from TunerStudio so yes the left axis is kPa. Colours are just for looking at :D

Honestly I don't think it matters which you use, probably the 127 one as it has a stock cam but would you be worrying this much about swapping a distributor across from one engine to another? :lol:

Hi Steve,

 

Tried loading a picture, but have not managed to work out how to do it yet.

 

Will try again tomorrow.

When you hit reply on a post it'll bring up a box (like I've attached) and you hit the choose file below where you're typing, it'll be high lighted in blue.

Then once it's uploaded, you can press the '+' to add it into the text, like here:

And then you can carry on typing!

Hope this helps!

Steve
