Thanks Colin.

Good point.......


I didn't know that..........

That I did know about Megasquirt but didn't think it was too significant.



Ok so far I want a system above Megasquirt but not to level of MoTec.
What's an easy to program & tune mid-grade EMS system? Lots in this thread to examine.
Anyone selling a system?

You can add knock detection to MS...I found a couple of pages about that but haven't implemented it yet.

Lizard928

This is correct you can add it. But it requires you to open up the unit and solder things on and make circuitry. This is not something I would recommend for the average user! That is the only reason I say that Tom.

This is something that some forget to mention....

Now you do

It is not very significat IF you do it properly. The calibration for the WB is much simpler with with controller.

I would recommend the VEMS unit for this. But if this is your first standalone system. I can tell you that you WILL need someone who has used this unit before to go over the setup with you.
If you are good with wiring you should be able to get the wiring done correctly.
But the initial setup will be tough.

Otherwise consider Haltech or AEM as I have heard good things about both of them.

I will second the vipec unit , very good value for the money.
With all the nice features.

Details guys..details...

Cost?
Features?
problems with implementation?
wiring?
etc...

The Motec 48 unit Stan was selling????

Almost Tom
I purchased Haltech E6X
http://www.haltech.com.au/index.php?...d=18&Itemid=15

Multiple Fuel Maps in 3D, Ignition Maps in 3D, input sensors are fuel and ignition modifiers. Windows base. Easy bar graph table adjustments.
Good support and has been around 10 years+

Good price for the universal kit: ECM, Harness, Intake and Coolant Sensor.

I'll document the install over the winter.

Cool..look forward to yet another alternative to the LH/EZK..

IMO if an aftermarket engine management system cannot provide sequential fuel injection, it's not worth moving away from LH/EZK with sharktuner, unless it's super cheap like megasquirt. The knock detection and individual cylinder retard capabilities of the stock EZK is really slick. I think my engine would be blown up by now with most other knock management systems.

What utter rubbish , the stock knocksystem while good in its day is over 20 years old , it is too old, to slow & picks up interference . If you are hearing the knocking you are already destroying your engine . Modern systems, the good ones are 32 bit, so they are already faster ,so there is not any comparison if they are tuned accordingly ,you are already ahead of the game . Tools are only as good as the idiots holding them. I wonder could you do your work with pc s from 20 years ago . I certainly couldnt.

There is no substitute for proper tuning , knock systems are only good enough if they are properly tuned . They are only an listening system, which is subject to all the interference and noise from the engine . If anyone has ever listened to what the engine is producing in the way of noise will know what Iam talking about .

Hmm... perhaps you can provide a concrete example of why the stock system is rubbish? My car has over 40k miles on the supercharger install with EZK and now that I have a sharktuner, I can see how much knock retard was going on in all cylinders all this time (no ignition tuning was done until now). Since the car is still running great, that to me is a clear example of how *great* the system is.

Comparing a 20 year old knock system to a 20 year old regular computer is just a silly comparison. You should be comparing a Cray from 20 years ago (something that was way ahead of its time) to today's computers. Yes, I could work on one of those

I didnt say the stock system is rubbish , as you note in my comments , you have obviously misunderstood , it is still good in its day ,and is such today, but doesnt have lots of the nice features of modern units, eg wide band sensor , if you want to run your hand built race motor to a higher rpm , you cant use it , , if you want to control your boost stage or stagger you cant, etc etc .

However if you want to stay within the stock parameters using the limits of the basic maps as JDS have provided , then by all means you can .

Oh by the ezk picks up interference & is slow to pick up transient detonation & thus slow to react to it , particularly when the detonation is caused by oil ingestion .How do I know ? because I listen to it through devices hooked to the block through noise cancelling pilots headphones , specifically set up for the task .
On the Dynanometer foot control is quicker then relying on the ecu.

Hope I have cleared that up for you .

I would actually go micro-squirt on a system like this. Super cheap but you will have to develop your own sensors and look to spend a day or two on the dyno. We run it on our SCCA ITB race car. It's un-complicated with the VW in the long run and gained a bunch of HP's.
