Nodiz / Megajolt map questions & opinions
Turbo Mini Forums

Right - getting close to starting the beast up and this
Is the base map I’ve been given and wondered what everyone’s opinion is

1293cc
gt17
phase 2 cam
8.3 CR
And fresh build so will need running in and the cam knocking in too

3 bar map sensor if that makes a difference haha!

Not sure on Nodiz but looks like a lot of advance for a base map.

There’s some MegaJolt base maps etc on here. Have a look around.

Firstly, how annoying is that having the load scale top to bottom Ergonomics would suggest it should go from bottom to top, IE Load increases, manifold pressure rises, throttle position increases.

Anyway, the base map looks a bit hot from 100KPA upwards (or is that downwards )

with your low CR, At around 200kpa, i'd want to see no more than ~24 degrees depending on how efficient your intercooler is.

at 100kpa it does still look a little hot. maybe 34 degrees or so there

Start safe, have it dyno'd and use det cans to listen to the engine for knock. Find either MBT or knock limit and then retard 5 degrees giving a good safe margin. Can only really be done on the dyno.

nodiz is wank

you welcome to my opinion

Yes i moved to the darkside

Lol why’s that & any opinion on the map?

And thanks sprocket, not having much of a clue is it a case of changing everything above those margins and following the same increments across the Rev range at each level?
Not looking to spank it pre dyno
(Already booked in)
Just want a safe map to start it and bed everything in before heading over

(Probably keep it under 3.5k?)

Hi firstly, load can indeed be flipped over by changing the numbers on the left, however, as most people start with using only 0-100kpa, it makes it an odd way round to tunr, thats why it goes from 0,0 at the top left, where the axis meet, like any other table, anyway moving on to the actual point :)

The timing along 100KPa will be pretty close to what a normal A series would run at WOT when naturally aspirated - just take a couple of degrees off to play it safe, then, the old school rule of thumb is retard 1 degree for every pound (6 KPA) of boost, though, as mentioned, it would be best to just not drive on boost until its been properly setup on a dyno. If you hear det when driving, its already likely too late, so do play it safe and back the timing off until properly tuned.

If there are good megajolt maps, you can use the Megajolt map import feature of the NODIZ, which spreads their rather limited 10x10 ignition table out to the full 16x16.

Also, use the NODIZ launch control for a pretty effective "boost build" type anti lag when launching :)

Hope that helps, and happy boosting!

Brett I spat my drink out, that was funny.

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

It’s that sort of blunt honesty that makes this forum!

Bahaha!

If something is worth doing, it's worth doing half of.
