Aircooled EFI question
HI
Im slowly rebuilding a Manx and have a few EFI bits & pieces gathered with the intention of setting up a regoed ITB dual sport type vehicle.
I currently have
Microtech LTX10 - Thinking about swapping for a Haltech
X4 ignitor
Dash
Loom
Crank sensor and pick up
The engine is an unknown TP 1600 ? Id like to run (and learn) EFI on the 1600 while I save for a new engine. I was wondering if I install the EFI
system now while the car is apart is it possible to retune the ECU my self when I repower the Manx with a larger aircooled engine ? Is it as simple
as adjusting the factory programme tuned for 1600 cc to run a larger engine of the same type ? I dont want to be tied to a dyno every time I change
something which is possible in the early stages of driving and setting up the car. As you can probably tell I dont know a lot about EFI ...
Cheers

you should be easily be able to tune small to moderate changes in the engine.
I am learning EFI tuning my self, its not that hard if you have a base tune to start from and good helpful community of users for your ECU, that is
really important, the support from other users and/or the developers. Have no idea how that will be with haltec.
you will however need a dyno to get the ignition map spot on, the seat of your pants can only get you in the ball park to say 90% correct if you are
real good. but that should only required once you got everything else more or less right
AFR map is the easy part, just get a wide band and that should be pretty easy to get right.

Definately doable. I have done many. It takes many hours to get the details right but each system needs to be learnt, and some are quicker to tune
than others. There's heaps of info online these days to make it easier.

What type of ECU have you guys been working with ?
Vlad from what I understand wideband isnt available on the microtech which is one of the reasons why I was considering the Halltech. A AFR gauge can
be added but it is for visual reference only and was expensive compared to a stand alone unit. I really like the idea of running wide band with a O2
sensor to control each throttle body. Probably over kill for a knock around buggy.
Thanks for getting back to me

That would be the best move you could make
I had MX8 and gave it the FLICK after numerous problems
best money you will spend also will save you heaps of money in tuning time

Never had a problem with any microtech I've tuned. Apart from me using injectors that we're to big and over powered the drivers, my bad!!! Then i
got them upgraded, which now come standard in new models.
Pm me if you want to sell the LT10
Or if you want info on tuning a microtech

I have Delco 808. bunch of aussie enthusiast created upgrades, tunes and software.
Nothing beats asking the guys who created the electronic and software.
Can also be used to control some auto transmissions. A fair few people have migrated over from haltec to delco.
MS is also a good one and apparently one of the best and easiest to use.

Yea, MegaSquirt reads as easy to tune and heaps of online info for it. Also the cheapest complete control unit I've seen so far and with freeware
self tuner you can pretty much drive the vehicle to tune the ECU maps unsing the ECU wideband to correct AFR.
Looking forward to doing mine

I've heard good things about MS but not seen or used any personally. I've done some CB systems, 1/2 a dozen or more Haltech's and am presently
working on a US SDS (Simple Digital Systems that Raby used to promote)

yup, been doing me research for the last few years on MS and for capability and cost I can't see why to go for more expensive systems. Only downside
is not getting a nice cast alloy ECU housing

about 300 or so aren't they?
My ECU also has a self learning VE mode too, real time tuning and logging. Cost 220 all up and I had most parts laying around already.
New programmable knock sensor and universal ignition module coming soon as well.

So it's a Holden ECU that's been hacked? Just had a quick squiz and the MS seems to have more straight forward info to read and a nice GUI to
programme the ECU.
Still it's a nice cheap option
Thing I like about the MS is they can run so many OEM engines using the OEM sensors and even has knock input and onboard 1 bar MAP sensor.

Yes its a hacked Delco 808, out of a holden but also seen in many other GM, some Nissan and opel,vauxal etc...
new development are allowing OEM sensors to be used, some already supported out of the wreckers/ebay
They feature now few flexible A/D input and output fully programmable to run your own devices and sensors.

How easy is it to programme? Done as assembly or statement list or is the software GUI based?

have a look, bit of everything really, depends on which path you take.

Hmm, interesting but think I will stick with the MS. The software GUI seems better and download doesn't need compiling into a bin file.

thats only if you are flashing the EPROM with a programer. if you use the real time setup it works just like MS, just download the apropriate user
made files and tune on top of them.
I found this heaps easier to understand than MS and one of the reason I went with it, I was originally going to convert mine to MS.
I suppose it depends on your way of learning and experience. I have a strong electronics background and have done micro controller programing before
so this seems easy to pick up. But I am also a PC guru but lack on the software side so naturally I find gui based stuff confusing sometimes and get
lost easy.
still the MS is a good choice, heaps more advanced, easier and flexible than the others like motec and haltech and a like.

I'm an electronic and electrical engineer so have done my fair share of assembly coding.
I was being a bit lazy looking at the Delco stuff but seemed the programming is having to change some form of binary language to make it work the way
you want. S'pose once you get a handle on the lingo it gets easier but the MS has good technical guide for the software and the GUI is pretty
descriptive for each field to programme.

Well definatley no turning back now Ive taken another step to injecting this Manx.This mission has to succeed as Im risking my manhood when my wife
see's the next credit card statement..
I ordered some throttle bodies and injectors. They should arrive within a couple of weeks but it will be weeks before I get a chance to work on the
buggy so no pics in the short term. I'll probably just hold them a while..
Debating what to do for a fuel system. Ultimatley I would like a larger aluminium tank with internal baffles ,pump etc.
But for now I have a Tee piece to screw in to the tank, like the ones supplied in the CB EFI kit. Is a surge tank really required ?
Still havent decided what to do with the computer.I followed up on MS from your replies but I think it is going to be to difficult and time consuming
to implement with my limited knowledge and free time. The new MS3 however looks like it is ready out of the box but its out of my price range. Either
way I guess 20bkombi/Aaron - I'll be in touch soon ..
Wish me luck

For your engine I'd say just the MS2 will be more than enough and is far cheaper than the MS3.
Gives you twin injector firing and twin spark firing. MS3 is only useful if you wish to use multi spark system i.e. coilpack on each spark plug or
want to go sequential injectors for lower emissions and better MPG. Bit more power there too
