Megajolt & Ignition maps

Postby Gilesy » Mon 19th Jun 2006, 06:53pm

Guys, I'm slowly building a pile of info and images for a megajolt article for the Tech section, and thought it'd be handy to have a database of maps and the spec of the engine's they're running with.
If any of you get a moment, it'd be really handy if you could get a screen shot of your map in the megajolt programmer, the map file itself, and as comprhensive a spec-list as possible.

Cheers dudes,

Giles

Yeah, I'm putting a list together of all the parts needed, and photographing the parts I have as I get them. So far I'm short of the VR sensor and trigger wheel, but I've found a Sierra in a local scrappy with them still fitted :-$
I won't go into the whole board populating thing - that's more than well enough covered on the MJ website, but I will try to cover opening up and de-pinning the ford connectors for rewiring/soldering, knocking up a home-made VRS bracket and the trigger wheel, mounting the coil pack etc.
When I first started looking into MJ it was a really unknown area to me, so I think a database of proven maps, and perhaps a set of "safe" maps to get people as far as the rolling road would make the whole proposition a little less alien to future noobs.

am i right in thinking this allows you to have a mappable thingy on normal carbs?

you can have a mappable thingy but the whatdyamacallit has to be left standard.

Basically gives fully mappable ignition on the cheap with the possibilty of injection aswell.

whatdyamacallit?

megajolt just does ignition, megasquirt can do both ignition and fuelling.

will the maps be using a throttle position sensor or a vac sensor? as I will be needing a base map soonish for a warm 1293 but I will be using a vac sensor.

I'm using MAP too, but if the users of said maps specify what engine load sensing they run (MAP or TPS), it'll make it nice and clear.

What is the size of the mtrix on a megajolt? my megasquirt is 12x12 and I've got maps for an NA 998 and a turbo 998.

The NA 12x12 you sent me was really handy - I drew the 3d Map in CAD (geek mode) and used the mesh to create a 10x10 for the jolt with some sneaky spacing in the wider spreads towards the top third of the map where it was already a little spaced.

Theres some photos in my journal if they are any use

Have started doing this conversion recently, well aquiring parts and starting to wire things up, but not actually fitted yet

Will be using a TPS with mine thou, so depending on how long it takes you to do the article I may have a TPS map for you

Brilliant! Do you have info on making the throttle pot? That'd be really handy, meaning we can cover both side of the kit.

Not done that bit yet but when I get round to it I will take some photos etc and let you have them to include in the article

No promise on dates though!


I know the TPS can come of a sierra or caviler about £3 from scrappy!

i have mine running megajolt on a map sensor. it can be tricky to fit in places but its definately worth it. anyone else noticed the motor will rev more freely and it runs a lot better.

one of the best mods for an a series i recon!!!

I've got a Sierra on my drive with a trigger wheel. You could buy it then take the photo.

An update. I just plugged my USB/232 bridge and connected to the jolt, turned on the power supply and IT LIVES
Image
How happy am I?! Even though I had to compromise on the odd component from what's specified, it works beautifully. I even trialled it by saving the basic map supplied and uploaded another. I'm reet chuffed, just need to solder in the MAP sensor and get the last few Dorf bits. I'm looking forward to this :lol:

Where are you getting the bits from Gilesy?

I have tried Alex a few times but he is not very quick to respond. I need the oscillator and map sensor + another couple of bits.

Guys,
If you would all be so kind, pleeeeease could you email me your map stuff to shadesofpoo<at>bodgetape.co.uk
I need:
Engine spec, particularly capacity, cam, CR, fuelling and breathing system and general head "spec".
Load sensing used, MAP or TPS
Map file (and info on which tuner program was used) and screenshot, preferably 10 x 10. I can convert it, but it takes a while so Id rather not if I can avoid it.
Thank you kindly,

Giles

Only time that i'd normally be flitting away doing nothing anyway!
As for cost, I bought the board, box and processor, and built it up myself (using what bits I could scrounge from work), made a full wiring loom to connect everything together (again all scrounged from work) and I got all the Ford bits from one scrappy (if you're lucky you can get it all from on car!).
I've kept costs down wherever I can and it's come to about £65 so far. That includes all the components to populate the board too. All I need to do now is fit the Sierra trigger wheel to my spare crank damper (£5 of machining) and make up a bracket to hold the CPS.
That's about £70 all in for an infinate range of advance curves and no more damp problems, dicky caps and rotors and no moving parts to wear.
The 123 distributor is a work of genius, but will still always suffer the usual damp distributor problems, and they're about 200 quid.

Hoe you thinking of fitting the sierra trigger wheel to the damper? its just I'm looking at this at the moment
