Crank Trigger'd 1200....

[andy198712]

Hi,

i havn't really posted here much but enjoyed reading, my names Andy and i'm from Cornwall UK.
i'm 24 and had my first bug now for 2 years and loving it! i've been slowly building a 2110 EFI motor to drop in, one thing i wanted on that was a crank trigger setup, so thought why not test it on my daily 1200!

the trigger wheel, a "rack shack" equaliser power pulley in steel flavour



using megasquirt for the brain and did the mods to that to run EDIS (simple place to start)

so i test mounted the sensor and left it there for a few hundred miles to see it was safe:





My brain and fuse/relay/EDIS board is hidden out of sight in the parcel shelf area



the MS ECU needs a vac signal also, so i drilled and tapped my manifold



i then made up a more solid mount from 10mm ally plate which doubles as a fuel pump block off.



started off safe with a map to get me going, this was better then the dizzy:



and currently running this one:



So, whats it like?

amazing! my stock 1200sp starts on the button using no throttle cold, with no choke needed and holds a steady idle, it cruises with about half the throttle it needed before, better pick up, went from low to mid 20mpg to 37mpg is my latest. no points or rotors or caps to wear out, no spark scatter ect...
i've gained what i wanted in that i'm not shooting in the dark when i start up my 2110 for the first time

i just need to make a dizzy block off and get that out the way. i want a super clean/bare look for my 2110, injection will be hidden behind the shroud ect.

cheers for now

Good work. I like your style of proving the setup on a stock 1200. Proof that even just a mappable ignition system makes a big difference to power/mpg.
What would be really interesting is to see how the same motor would perform with fuel injection as well. I bet you could get a massive increase in mpg!
I wonder if you could get a set of injectors from a small modern car? Or even single point injection?
I guess being single port running four injectors would be too much work.

Thank you 

indeed it would, i think with a single port you would need to either go single TBI, which would be a benifit i think, what with fuel cut on over run and other tricks but you would see more from individual injections like you say, on a single port that isnt easy, but far from impossible, it think mega squirt has a siamese code for that.

i think ideally you would swap the heads for the 1300TP ones, then you could probably make the best of the small engine, especially if you had individual tuned runners, heck even a small turbo maybe....(i forget who made the turbo 1200EFI but it made alot of power!)

for single port i would have thought running twin carb singleport manifolds and two TBI or using weld in injector bung would be the best bet.

But... i'm getting close to being albe to build up my 2110 which will be EFI so i think i'll back burner the 1200EFI (i did see small bike ie125cc TBI's which look ideal but unsure they would be up to the task? anythoughts?)

i might make a 1200TP EFI though in the future, that would be cool!

weldings a couple bungs into a single port manifold wouldnt be hard though.....

i really should stop thinking out loud

Andy,
Nice job, I have read a little about doing this conversion. Did you go to individual coil packs? Wasted spark? Any advice for others looking to do this?

Thanks,
Jeremy

i went for the EDIS route, taking parts from a mid 90's ford, its the easiest route but not the best. ford coil pack, ford sensor ect
and megasquirt 1 version 2.2, again the basic one

made up my own plug wires from a kit from "megasquirt v8" a uk company.

My advice, unless you want the dizzy for looks/nostalgia (which is fair enough) Absolutely do it!!! your chucking away money and power not doing it.

EDIS cant do rev limit, thus if you want that, and launch control, anti lag ect what Megasquirt can do is unreal, but you have to let it fire the coils (which i'll do soon i think) and not run via the EDIS module.

has anyone seen a 1200SP pull away with launch control??   (NA, no point i know)

it took a fair bit of reading and research for me to get here, "i dont do electrics" but its actually pretty easy once you get your head around it.

and hey, i wont, but i could swap back to a dizzy in under 5 mins.

i should add the ecu will control fuel, spark, boost, water, fans, idle vales ect, you name it, it will run it

[andy198712]

also it doesnt have to cost a bomb, mine was like this

ECU £80
EDIS unit, coil pack, sensor £20
Plug wire kit £24
Ally plate £7

you need a trigger wheel, i got mine for £40 on ebay but you can fix a wheel to any pulley, there's loads on ebay or have your pulley machines to BE the trigger wheel, although it may have to be steel?.....

Andy,
How does the system linked bellow compare to what you are running short of it is megajolt and not megasquirt?

nice work, i am actually also doing it on a stock 1600 now, also at the same time carb to injection, let it run before i put in the bigger motor.

Hi,
Just that megajolt will only run ignition, megasquirt can run fueling too.
If its just spark then megajolt will probably be easier? I think MS can monitor and control more sensors bit if you just want ignition why bother
And if it's cheaper....

Hope that helps

Nice! What's your injection spec?
What ecu?
Who mod'd your crank pulley? I'm thinking of a hidden setup for my next one

ecu is Haltech Platinum Sport 1000

crank pulley machined by JMR , sensor mount also from JMR in UK, way back in 2001. 

might be going for fully sequential, MSD individual coil packs, oem coil pack if waste spark,  i aint the one fitting it, sent it to a shop.

what are you doing injection wise?

nice setup! the JMR website is pretty out of date but his work seems to be top notch!

45mm jenveys, all the basic stuff when converting to efi

[andy198712]

are the injectors in the throttle bodies or mounted in the manifolds? most of the JMR's have been in the TB's and i'm thinking of going that route...

in the throttle bodies in my case.

this is another pic i borrowed from a car in the UK

theres a lot and long discussion on this in STF with regards to the placement of the injectors, nowadays i dont care and just use what parts i have. as long as the car runs and it poproduces hp, thats all that matters to me for now.

i feel the same, i mean look at the stock setup for a vw, the fuel enters the air stream about 2 feet from the valve!

so from swapping from a 112 to a 120 main jet due to being a bit lean i thought, i've dropped to 33mpg.... might check my plugs again and see whats going on, maybe try something inbetween.....

another job is to let the ECU control my fuel pump also

Good work going on there Andy, aer you going to the jamboree next weekend??

I've been thinking about Efi on a singal port.

sam

thinking sat yeah, how about you??

i think you would really need to put the injector near the valve for it.... i got a thread in SFT on it..

Seen the thread on stf and thers some good info.

Should be ther from friday, in the bug tho as the bus is broke 

[andy198712]

arh gutted! was it the engine? cool whats your bug look like? i'll keep an eye out

[andy198712]

updated map, 36.16 mpg



i think i need to play with the carb a bit but tbh i'm not very good at carb tuning!

[andy198712]

adjusted the map a bit....

[andy198712]

Well I chickened out and tamed my max advance a bit till I get a cht or egt gauge.
Just filled up and got 38.5 mpg, best yet!
Wondering how I can break the 40 mark with this setup....

[andy198712]

well, just filled up and broke my goal of 40mpg!  41.57MPG, very pleased!

[andy198712]

Been a while and still running spot on daily,
My current map


I'm getting 38mpg avg but would do with trying harder!
