Smart injection

[Kapt. Q]

The injectors are rated at 148cc/min at 3.0bar.


Here's a link too the three injector types Smart used:

You are very resourceful, great links.

I have shipped the system to you yesterday, should get it sometime today. I like to move on to the next stage. Do you have a link to the ECU pin out for me to make a wiring diagram?

[Kapt. Q]

Hi Richard, you are very quick! I sent you a PM at the same time you posted this, lol!

Very impressive service!

I will get you a link asap!

Cheers!

Mine is the 700cc one

All credit must go to Eviloution, the brains behind the website I have linked to many times, a pioneer in Smart modding and assembling all the information Smart never released to the public that makes it easier to work on them, there is still no publicly available workshop manual for them. His site is an international Bible in the Smart world.

Cheers!

Hi Richard, it has arrived like you said it would.

I take it I will be using two secondary injectors post intercooler?

I'll post pictures of installation as i go along to make sure you think it is optimum.

Cheers!

One pre- and one post-. I just send you a spare one when higher flow is needed.

I am sure you will make a nice job of it. Keep me updated.

Keep me updated as well . If I ever have to move back to Japan, a smart is high on the list.

[Kapt. Q]

I will definitely keep you all posted!

Progress is steady, a location has been chosen for all parts except the pump and tank, but I may have an idea for those.

My problem is that you need access to the complete floor of the rear luggage area because this is where the engine access hatch is. I think that I will have to attatch the pump and tank to the pickup truck style tail gate that it has, so when you open it the tank and pump come with it, swinging out of the way of the engine hatch. This will probably require a custom tank because of filler neck position, or at least a check valve on the vented cap? I also would like it quite resilient in case of a rear end shunt.


(not my car, but good picture of luggage area and hatch, engine is under carpet in back!)

This then causes other problems like mounting the sensor and pick up on the rear of the tank which will require a litle surgery on the internal plastic tailgate panel.




Richard, Any progress on the failsafe wiring diagram? Do you need any more info? It is the one part of the installation I am not confident about because my knowledge in the field is limited, and so am truly grateful for all the help.

I should have some progress pictures shortly of the 'Angry Midget', lol

Cheers!

Ps. Disassembly of a stock intercooler has shown serious restrictions within the outlet arrangement making me more eager than ever to see if perhaps we can bin it altogether.

I am thinking of trying it with and without intercooler with the injection on the dyno. This would mean fabricating a new intake between the turbo and TB but then I could locate the primary post turbo jet closer to the turbo for improved charge cooling and perhaps add a third smaller jet closer to the throttle body?


If it turns out that it is not possible to do all the charge cooling without the intercooler then I will certainly replace it with one that does not have the restrictions.

I will do it this weekend. Things are a bit busy here, all good.

Hi Richard, no pressure, the tank fabrication will take a little while anyway, I'm just eager!

Most of the details have been worked out regarding the tank as above but rear mounting the filter outlet and level switch is problematic because of the crash bars within the tailgate (great for the mounting though), perhaps it is not needed if we put a 'sump' in the tank and some baffles???

Cheers!
