Hello All. I've got my brother too build me a programable Ecu to suit the Gti which fits in the original case.I've done quite a few k's now and have a map that has given me better fuel economy and smoother driveability. We are looking for 3 people to help with the development of the Ecu, it will cost you $300 and you'll need an ecu so we can fit the new board in. We will give you all the programing software and any help to get you going. Any input and ideas for the development, changes to suit your requirements will be taken on board. At he moment there is a bluetooth setup in the making so you can use your phone or ipad etc to do your programing or your laptop,cliffs just working on the software but we have already got them communicating at the moment. Also we are about to mod to fire sequential injection and a set up to remove the dizzy cap to suit sierra set, which is what I have it running on.This setup will require harness mod but the setup we have at the moment is a plug straight in. Next mod for me is a 5 wire exhaust sensor to provide better open loop control. All aspects of the Ecu are adjustable,Future mods will be to adapt too my Datsun 1600 L series engine and turbo setup for the Gti.Any setup you wish can be done if your prepared too do your own R&D.So you get a programable Ecu for $300 which is an absolute bargain, plus any upgrades or mods at little too no cost depending on what you want. so leave your input or contact me on 0418475652

Can I ask why you have deleted your posts on redline??? it's an interesting project.

You can get a Megasquirt for less than 300, why bother?

Take it easy there G-sus...we wanna promote independent thought, not stymie it.

Why would someone spend over $10k to get their 1.3 swift up to 150+hp when they could just buy a used WRX? Same principle applies.

Furthermore, a megasquirt requires a harness to be built, plus the version that is <300 does not control fuel and ignition afaik (stand to be corrected). This, from what I gather seems to be a plug and play drop in....I have seen the move toward this from manufacturers such as Link EMS (New Zealand) which seems to be pretty popular in certain car communities.

Why not give the guy a chance to show what his creation can do, instead of condemning it outright ?

:salute:

This ecu is a variation of Cliff Jefferies motorcycle ECU, by the looks of it he's spent the last ten years working on and making ecu's to replace the unreliable european oem ecus.

http://www.jefferies-au.org/MyECU/

The fact that Trevor owns a suzuki is good for us, I think a dedicated ecu kit which reads factory sensors and has a good base map would be considerably easier than megasquirt, the problem with megasquirt is it's so flexible and configurable is quite hard to know where to start.

Yes Link has been making plug in ecus for quite a few years, mostly wrx's, evos, gtr's and a few other performance cars, adaptronic seem to be the only manufacturer with a plug in solution for our engines using their special loom adapter

If I owned a road going swift then I would certainly look at a jefferies ecu but since my race car is partially associated with the NZ distributor of Microtech ECU's and also in a high state of tune I'm definitely not touching anything to do with the ecu or mapping, it's perfect and my new season starts next month. :mrgreen:

Not condemning, I'm just saying :) Though being a PnP setup I can see the appeal, it all comes down to how good it will be. Guess we'll wait and see hopefully :thumbsup:

you have a pm.

having done the megasquirt thing, i might make a good guinea pig. :blackeye:

Thanks all for the replies, forgot to put the link to cliffs web site.( http://www.jefferies-au.org/MyECU/). This was only done for my bennifit for my own projects. We are just making it available to others if there interested.I myself am very impressed with the Ecu and if you get pulled over for a RTA check they won't know the difference and no defect.Cliff is constantly upgrading and keeping up with technology.No interest on redline so came here,I'm not going to waist too much time if people are not interested or negative.The software is what makes this good.I'm pretty sure cliff has showed this to the programer of mega squirt and he was pretty impressed with it.

Thanks for posting.
I will move this to the correct forum, and make it a sticky for now. Hopefully there is interest.

trevorj, my car isn't even on the road properly yet and I'm interested. My only concern would be how intuitive the software is, since I'm a technology simpleton with a basic understanding of efi tuning. Thing is, I'm a hapless DIY addict and I can't stand the thought of anyone else programming my ecu...kinda like someone else screwing my wife (after all, she's mine right? And like my car, I've got the credit card statements to prove it.)

Is this for me?

Hello PBC137, I'm a mechanic but move to other trades 20 year back, I learnt and am still learning, basically we will help as you go.The map is in a basic notepad spread as below

# TDC is the pulse count for TDC power stroke of cylinder 1 ( i.e. When the spark fires
# CylOffs is the number of degrees between success cylinders ( 0-720)
# PulsesPer is the number of pulses for the 720 degree 4 stroke cycle

MyECU Cfg TDC=0x1200, CylOffs=180, PulsesPer=24, NOTE: THE MYECU IS CLIFFS BIKE SETTINGS MissingPulses=0 # CoilCharge is the period in us for charging the coils. 0 for cranking, 1 for running
# Warning, Setting coil charge too high can cook the output transistors and coils

MyECU Cfg CoilCharge0=4000,CoilCharge1=2700

# Pressure - mV and mB values defines a line representing the air pressure conversion

MyECU Cfg Pressure=5000mV,1024mB,5752mV,1060mB

# There are 8 possible voltage targets available 0-7
# The first number for 0 should be 0.0 and means open loop
# For simple sensors where richer is more voltage, all numbers should be positive
# For later sensors where leaner is more voltage, all numbers should be negative

MyECU Cfg O2=0.00V,0.50V,0.50V,0.50V,0.50V,0.50V,0.50V,0.50V,
# 0 = None, 1 = Inp1, 2 = Inp2, 3 = Both
MyECU Cfg O2Sensors=1

# RPM specifies the maximum RPM.
# TPS specifies the throttle value at idle (no fast idle).

MyECU Cfg RPM=8620, TPS=64

# TDCWhileCranking=1 will fire the spark at TDC
# TDCWhileCranking=0 will fire with advance from the map

MyECU Cfg TDCWhileCranking=1

The Ecu progam allows you to create log files which you can colourize to tell you your rich lean statis.
Initially if you just play with the inj dur (injector duration) learn how to load map and ecu diagnostis, which is to log files, then colourize and you can see if your rich or lean.You can also go to cliffs web site and learn there.
The forum that runs from cliffs web site basically has everyone helping each other.That's why we want some peoplle to get involved so we can all learn off each other. I increaseed my fuel economy, and It pulls up hills better and drives smoother than the factory. The map you'll get intially is the one I've been working on that suits my sierra/gti setup running on 98 octane.(thanks Nsw gov for the ethonol in all fuel which lost a lot of my economy in the first place
I'm not saying it's not for you but would like people that can help with development and other mods they would like
The above map didn't copy over too well so the columns are a bit off

Hello everyone. I've just joined the forum so that I can help clarify some points and answer any questions.

The MySwift, as I have named it, is the next version of the MyECU range that I started back in 2003. As such the ECU firmware is quite mature. Much of the hardware is from the other versions also so is reasonably well tested.

The main criteria I had in designing the MyECU was to keep it simple.
The MySwift is a plug in replacement.
The map is a single text file that can be editted in notepad if desired. You can read about it here - http://www.cajinnovations.com/MyECU/maps.htm

The ECUController software that runs on a Windows PC, doesn't need to be installed. Just copy and run.

Keeping it simple doesn't mean I've skimped on features. You have full control of spark advance, injector duration, even injector advance ( although that's not available on the standard swift configuration ). The MyECU will run with any gas sensor so you can easily change the cheap narrowband one in the swift with a current wideband sensor with not too much effort. You can set different lambda targets in different parts of the map.

With respect to the offer of a MySwift ECU fitted to a supplied original ECU, rather than 3 persons it will be some small number of persons with technical ability. I'll make up a batch of circuit boards to suit the interest. The $300 is a special price for this run only. I expect the final price to be in the vicinity of $500 for the upgrade of an original ECU.

Apologies if this post is a bit spammy.

Cliff

Thanks Cliff :thumbsup: and welcome to Teamswift!

So can you decode the stupid suzuki distributor or do you have to cut the extra small teeth off like some other ecu's?

I am using the standard distributor at the moment but because it doesn't give a way of knowing exactly where the engine is positioned, I must send the spark through the distributor as the current setup.

To do some of the enhancements planned like eliminating the distributor cap ( dual coil etc ) or sequential injection, a new pickup scheme will be required.

It may be possible to to do sequential injection with a wiring harness modification only. For instance it may be possible at idle to move the injection around and infer the injector position by the efficiency.

These benefits are 2nd order gains though. The main benefits of adjusting the mixture and spark and putting a decent gas sensor on are available in the current configuration.

Could you cut one tooth off and look for the missing pulse as a way of crank reference? easier than mounting one of those edis wheel thingy's :lol:

I ditched the whole dizzy and used a complete toyota dizzy with a small adapter, it has 24teeth on the top wheel and two wheels underneath with one tooth only so I could run sequential injection, works well and is much lower profile, we've done this on a g13b rwd starlet as well.

I think removing one tooth is the plan, cliff just had to work out which one?

Cool, with the stock injectors harness only being 2 wire are there any plans then for an extra mini loom?, maybe one for injectors and one for coil over packs? that way it's still stock plug in and it's easy to wire two small looms, couple of spare pins for earth connections?...

Oh and Richard you need to remind these Aussies you only have 3/4's of an engine :lol: not very common in this part of the world 8)

i have a friend who might make me the owner of his gt parts car. the blue vert is all megasquirted up and the current black monster turbo3 is still on the bench. the red vert will probably get the quicker gt swap.

translated, i can run the stock ecu for the twincam or i can play. :ez_pimp:

i'll have to look at the code for this standalone. it's indicated on the web page that it's open source and there's documentation. from my megasquirt system i plan on using the same 3 tech underdrive pulley with a concentric 36-1 trigger wheel, hall gear tooth sensor, flying magnet cam gear with a hall effect unipolar sensor, and the little hed conditioning boards i ginned up for the blue and black turbo3 megasquirted engines.

i'm more interested in the ability of the processor to give me 4 channel direct fire ignition and 4 channel sequential fuel injection.

i have another question. the thread mentions connecting a 5 wire o2 sensor for closed loop operation. currently, what's serving as the input for o2 sensing? i can generate a 0-5 volt signal or a simulated narrow band output from my afr gauge.

That's sounding like quite a departure from the standard swift.
I'm not sure if you are talking about timing inputs from both the cam and crank or just the cam.

To answer your questions. The firmware is currently generating 4 spark outputs. At the moment they are just mapped to a single IO pin. To produce 4 independent outputs is simply a matter of laying out the PCB to provide those. I'm not sure having 4 is better than having 2 in a wasted spark scenario. If it was I'm sure the japs would do it for their 4 cyl bikes.

MyECU can handle either of the o2 outputs you refer to. It only cares about the target voltage you set.
