Sounds like you are in the middle of the development work.

Just some thoughts.

Pugs at the right heat range

Are the injectors too small?

I've gone from 8's to 6 and now 5 - all the same



yeah - I didn't point that out, the injectors at 100% means they are turned on all the time to supply the fuel it needs. I thought they might be too small from the start, confirmed it now...

I had a similar issue with the plugs when I went to mega jolt. However it wasn't the plugs, I haven't shielded the vr sensor wire at both ends. I did this and never had an issue since.

This caused backfires, missing. So it might be worth checking the plug wire is shielded and the shield is rather at each end, on a clean earth.

Good luck it sounds like it going to be great.

interesting you say that - I haven't earthed the shield on my VR sensor wire. Been there 4 years or so, and this issue has only appeared since I put the injection on. It's either that the injection has upset something, or the carb fuelled it's way through that spot.

I might do that Graham, thanks

I earthed the shielding on mine through the edis connector. I pulled one of the unused pins out of the connector, and put it in the pin 7 position (shield ground). No dramas so far.

If you need another coil or edis to try, think i've got some spares here.

Andrew

I think you are only supposed to connect the shield at one end?
Check your install instructions first, and yes I connected my shield wires at the Edis end.

just an update on fuel economy.... driving back from Hay (all flat 100kph roads with a few small towns) it did a steady 7.3l per 100km

best economy I've ever had out of any mini

Nothing to do with leaving your roof rack home?

nah, I actually haven't had the roof rack on the car for 18 months.... and 3 weeks ago it was using 45l in ~300km

So Simon, What did you do to fix the problem? New injectors or a combination of different things?

Haven't fixed the problem, I'm just driving around it for the time being. Before Hay I had a little problem where it'd die off idle, but I bumped up the fuel there and it's OK

Andrew kindly loaned me another EDIS unit, but that didn't make any difference. I earthed the shield for the VR sensor, no difference there either.

I'll sort myself out and install that other Haltech, ideally I would like to set it up with a megasquirt, but that'll have to wait for sufficient funds

lol and the thing is supercharged lol thats awesome!

Hey Simon I'm contemplating going down this path. I'm looking at a set of bikes throttle bodies matted to a weber manifold. Reason for the bike carbs is for $150 I get a complete package. Just need to get an adapter cut to mate the TB's to the weber manifold.

I've asked specialist components is they sell their ecu package sans their throttle body to really simplify the install. I don't trust myself to take on a mega squirt but if there was a complete, bolt on kit I would buy it. The megasquirt kit suits as that fella has developed the code for the siamese port. Additionally what I would get is a second set of injectors sunk into the weber manifold so the setup would be capable of staged injection (which his code supports). Alternatively the aforementioned spacer could also house the second set of injectors.

Question, what are you using for a crank angle sensor?

Hi JC

AFAIK the specialist components stuff will only work as a single throttle body, it won't handle any sequential injection - it can't, as there's no cam angle sensor. To do sequential injection, which is what you need to do for the siamese port issue, you've gotta know which cylinder you're squirting into, and you can't do that without a cam angle sensor... therefore the specialist components computer won't handle 2 throttle bodies



Jean Bellanger (that fella) developed the code (sequential injection with individual injector timing control) with a MS V2, and the code has been fully integrated into the official software on MS V3.

You can buy one built, and I'm sure it will pretty much "just work" once you've nutted out what needs to go where... I did build one for a guy to put on a V8, but he's gone to ground

I don't mind doing the R&D to make it a bolt on kit, how cashed up are you? you just have to buy one for me and one for you



still running megajolt ignition, so the ford edis unit, with a falcon VR sensor pointing at a 36-1 trigger wheel on the crank pulley. Talk to Ben aka 92 if you want a trigger wheel, bracket & sensor - very cheap from him. The same hardware will talk to an MS3, from memory we just ditch the edis unit and the VR sensor plugs right in to the MS3

Cam angle sensor is easy - there's a very simple solution for us. Someone on turbominis just drilled and tapped a thread into the cam pulley, and put a cap screw in it, then mounted a little screw-in inductive switch in the timing plate that lines up with the cap screw - it would work like a champion. We use the same type of sensor at work (I'm looking at one right now) and it's well up to the task. The cam in an engine doing 10,000rpm is only turning 83 times per second (Hz) - these things are reliable up to 5KHz so it's not an issue


that's what I reckon anyway

I've been busy again - ditched all of this - EDIS unit, megajolt, haltech, external map sensor for haltech, spaghetti wiring :



and replaced it with this - megasquirt 3:



and ditched this - hyundai coil pack:



and replaced it with these - individual GM LS1 coils - massive sparks:



and added this - wideband AFR meter with a nice little gauge under the dash, obviously it connects to the megasquirt too:



whole lot was a bit under a grand delivered from USA


I've been away for work so hadn't driven it till today, and it's much nicer than it was with the old junk.

The megasquirt tuner software has an 'auto-tune' mode where it looks at your AFR target in each load/rpm position, and adjusts the fuel to meet it. So you drive around with the laptop on the seat beside you, and it adjusts the fuelling by itself. When you're happy-ish, you stop, clean it up removing any peaks or dips and it should be very close to spot on, then you can fine-tune on a dyno. I did that for a while today, very very smart.

I have some more very snazzy stuff in the pipeline that the MS3 makes possible
