that can go for any ecu not just omex, you would pay that for an emerald inc fitting and mapping

Just been looking into costs of the VEMS and MS2 and the MS2 comes out about 1/2 the price. Have i got summat wrong?

Carbs and MJ would be interesting, don't know if i've seen that done anywhere on a k head.

Don't know about the cost though because you'll have to buy the inlet manifold and carbs which could cost more than buying an ECU in the end

I could knock up a manifold a piece of p!$$, ive been offered a K100 Head and Throtts for £125 Delivered. So im weighing up the costs.

Schrödinger's cat - so which one am I ???

Are they Amal carbs? And i think i see the dizzy in there still just no leads.

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

Yeah dizzy too!

Innovate LC-1 with a lambda sensor is $200 from diyautotune and you can get MS fully built or as a kit from there aswell.

IMO if i ran it on carbs i'd still want the LC-1 to keep an eye on the fueling.

Some one mention my name?

Yes I damaged the WBo2 circuit on the first board, but that was my own fault, not the fault of the board. And yes, I have had issues with the replacement board, which, to date, no one has any idea what the prime cause was. This only one of hundreds that have cause problems, same for the first board with the WBO2 problem. Its very un common.

Shit happens! bu it helps if you dont modify the boards outside of the recommended build procedure

what you have to consider is that while you can buy the major parts of the VEMS system and assemble them yourself, It all depends how confident you are and TBH how experienced you are with assembling this sort of device.

Personaly if I was to buy another, I would buy it assembled. You get better advice from the developers as it is a product they know, where as if you assemble it yourself, anything could be wrong.

Yes the VEMS base unit is more expensive than Megasquirt. But as has already been pointed out, VEMS has a built in WBO2 controller, and depending on options EGT inputs, knock retard, up to 8 injector drivers, up to 8 ignition drivers. loads of low current outputs for relays and lamps, and aux analogue and digital inputs. Firmware now fetures switchable configuration, not just the Fuel and ignition tables but the whole config! all other features are pretty much what you would expect from any other ECU

It really is down to personal prfference.

Do consider the dyno operator, and what has been said about getting it mapped. Any of the well known ECUs you wont have a problem. None of them will have heard of VEMS, except for maybe a few. A good dyno operator will not turn you away as long as you know your way around the tuning software, and what does what.

I have had experience of the DTA, and I would If i had to buy one of those over the Emerald

Depending on how quickly you need the ECU, you may wish to consider this:

Sort of a VEMS equivalent.

Coil on plug is deffo a bonus as it saves quite a lot of space under the bonnet surprisingly :)

Yes,

I mentioned that earlier in today's thread... and about a year ago !!!! (I think that was when I nearly started a war).

Early 2009 ????


Having said that, if it will add onto an existing MS2 (3.0 board)....

After all, these projects take a long time.

EDIT, typo

Schrödinger's cat - so which one am I ???

Oh its not an instant project, i have the engine to build. Then the Fueling to contend with.

I Might just buy the head then buy the carb/tb later on in the build!

Does anyone have any decent suggestions for the carbs??

twin40s seem a bit overkill to me?? Maybe? What about some bike carbs similiar to amal ones or similair to the original throttle bodies?

go injection. I am going to use teh SC ECU for ease and the fact that it is really powerful at what it does and it doesnt need a lamda sensor either. although one can be plugged into the loom.

I was originally thinking of using carbs but soon changed my mind.

I agree, also the fact that you get the tb's with the head makes it a no brainer in my mind.

Put them out for the Bin men

Seriously, with all the expertise available on injection it will be easier than getting carbs set up properly.

oh and have a look here: http://www.efiminis.olicentral.com/index.php

software wize , having mapped matts turbo 16v on the rd with a innovate lm1 and aux box ,it was a pretty logical progressive process ,and made a big difference to the car ,

between vems and ms i cant really see a diff when mapping ,the software is pretty easy .... i dont really understand why the rr's out there are so wary of it .


the biggest prob with the vems was getting the initial running setup created in the ecu ,but once its a runner its no prob , as long as you have a way of logging your mixtures ..


timing wize , i had to use experience and seat of the pants in the time frame we had ,so thats where it would really benefit from a rr session ,you could do it on the rd , it just takes longer to compare accel rates to home in on the best timing ,although ,since its replicating real world ic wize , it could actually be a more accurate if much longer way to do it , you need a really good big bog off fan on the rr to replicate the ic performance as it would be on the rd .


personally i would get the ms in kit form from diy autotune ,for under a 100 quid for the cheapest one id stick it together myself and work within its limits ,which i dont think would really limit me much , i think denis did this ?

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

My advice would be keep an eye out for a second hand proprietory ECU e.g. Emerald, DTA, Omex, can be had for around £300. If you're not mega into electronics etc this is the easier option in my eyes, all you need to do is buy a new plug and make a loom.

robert,

did you use the megalogviewer program? (if it works with vems that is)

no joe ,just used the tables and my data logs off the innovate .used matts senor and calibrated the innovate to that .

Getting my 1275 running on the MS was a doddle.

Once we loaded the Siamese code it became more complicated as we were then trying to time the injection point and fueling amounts.

Sturgeo came in useful for once ! I drove whilst he did the mapping.

Once I fitted the 998, it was just a case of setting the Megatune to "autolearn" and it set the map to the target AFRs. Needed a bit of tidying afters but still realtively easy.
