SuperMID availability
 

Hi!

I'm new to this forum, and have been looking for a forum like this for ages. I have also been looking for a device like the SuperMID for ages.

I was just wondering - how would I go about getting hold of one of these? My car has the right spec (electric signal for speed, and fuel injection). I have sent a PM to Yoshi, but he hasn't replied, but has been on, so I assume this isn't how to order one :)

Any ideas?

Thanks!

Matt

Hi Matt,

Sorry about my slow response to your PM.
I was away from home and I have to check my stock of the SperMID.

I have a few of them right now. You'll be treated as the first priority customer.

Anyway, I'm planning to do mass production and miles/gallons display capability in a few months. And, maybe lower price then...

Regards,
Yoshi

Thanks for the quick reply :) If you PM me the price, I should be able to buy one either in 7 days (if I can afford it, which I'm pretty sure I can), or in 4 weeks + 7 days (the following paycheque!)

Doing a huge mileage in a car giving <30mpg means it will pay for itself pretty quickly!. (It is roughly $800 / month in US$)...

I may even find customers from 2 other car forums I am on, once I have it installed and have much better economy from it! (I have seen threads talking about this a few times by different members).

Ime interested in one of those :D (mpg + lower price)
Please keep in touch.

DITTO.

I am also interested in a cheaper one with MPG + lower price... And will buy one (or probably a few). But, I am also interested in getting one of the current ones - it will pay for itself within 1 month of using it, most likely :)

Any updates yet Yoshi?

I'm very interested in one of your superMID's and if you can make them give a read out in MPG I'd buy one.

If he made one more versatile (MPG readout, an input for the # of injectors, etc) I'd buy one too!

Hi all,
Sorry for my slow update.

I have several of the original km/L version of SuperMID now.
Please PM to me if you are intererst, first come first served.
The MPG version will be available sometime in summer, I hope. :)

Yoshi

Thanks for the update, Yoshi. I will hold out until summer for mine.

The best thing about km/l and mpg is that it is a simple ratio to convert between the two :).

10km/l = 24 US mpg
20km/l = 48 US mpg

Which means that you will very quickly get used to the different units, and,
it will make no difference in the functionality of the device. So you don't necessarily have to hold off getting one until the MPG ones come out :)

I agree, I never had a problem with mine.

I'm just holding out until summer because that is when I'll be able to afford it ;) I'm not scared of any conversions. I work with computers all day, lol.

And... my SuperMID got installed today and works fine :) It was a bit of a mission due to my car's strange injector setup (pulse width modulation), but Yoshi designed a mini interface box which sorted the problem perfectly!.

I'm now in the calibration phase, which should be completed tomorrow (I have a long drive tomorrow). Looking forward to an increase in MPG :)

Hi landspeed and all,

It was a little tough mission to interface the pulse width modulation injector signal for his low-impedance injectors.
https://www.acceleronics.com/faq.htm#2
The SuperMID is designed for a standard high-impedance injectors which drive pulse is simple single pulse.

We had two approaches to filter his injector pulses...
A: analog CR (capacitor and resistor) filter
B: digital microprocessor controlled filter

He tried the approach-A, but no good result.
I tried the approach-B and it worked.
Please refer to attached chart.
The top green signal is the original output from ECU.
The middle red signal is after voltage shift(12V->5V) for filter input.
The microprocessor watches the pulse state change and counts 0.8 msec timer.
If the pulse state did not change in 0.8 msec, the pulse is good, then output change to meet the input.
If the pulse state changed but it was shorter than 0.8 msec, the pulse is ignored.
(The actual microprocessor has jumper setting to change the ignore period, 0.2 to 0.8 msec.)

So, the SuperMID M-1 is now working with such low-impedance injectors.

Regards,
Yoshi
