Re: Smart injection
It is very exciting as I know of no other car with it and I've seen a lot of Smarts, and if it has been done I doubt it has been done properly!
As you say it seems the perfect candidate. There is a fanatical Smart Roadster community out there and if it works out it may well generate some interest and also with the serious fortwo modders. (I have a Roadster too but I prefer the little fortwo, 100kg lighter, lol). The car will be going to Smart Times in Switzerland this year, as it went to the one in Antwerp last year, over 1140 were in the parade, lol. I have seen some intrest on a forum in injection for the very similar 800ccTDI they made. I have ordered a Brabus 101 wastegate acctuator, it has a stronger spring and allows overboosting beyond 1.5bar (with ECU adjustments). Once things are dialed in with the injection it will be interesting to see what is possible without stressing it much more. Cheers! Last edited by Kapt. Q; 20-01-2013 at 01:09 PM. |

Re: Smart injection
I have done a lot of searching for a suitable tank which must be located in the cabin.
Ideally I'd like about 6-8l min capacity because we travel quite a bit. I also I require a place for the pump next to the tank and then a place for the relay, the location it will go requires that it be somewhat protected, but still allow me to monitor the levels. The only all in one solution I have found is the Howerton Engineering 2x1 gallon tank and pump enclosure with led and fan, it also comes with a lot of style . Can I order this from you Richard or do I order it direct from them? Cheers! |

Re: Smart injection
You need to order the tanks direct from Jeff. It is simpler.

Re: Smart injection
Can you explain how do you control boost pressure.
It will be fun to get this car fully integrated with aquamist.

Re: Smart injection
Here's a link for a diagram of the engine setup regarding turbo and wastegate, etc:
http://www.evilution.co.uk/145 As you can see a boost control solenoid is operated by the ECU, which is also capable of a safe mode if it detects overboosts beyond a programable level or some other engine fault like a misfire, etc.. To boost above 1.5bar the actuator must be changed too. Here's a link with more detail of the wastgate control plumbing: http://www.evilution.co.uk/580 two lambda sensors are used, one in the turbine housing and one post cat. Last edited by Kapt.

Re: Smart injection
OK, got the answer. Boost a electronically controlled by the ECU via a BCV. Sorry for keep asking the same question
. Question: How you you alter the boost pressure? I like to know this so I can advise you how to reduce boost in the event of a failsafe activation.

Re: Smart injection
I think that the boost pressure is changed by reprograming of the ECU and perhaps an adjustment of the actuator depending how big the change is from stock.
It is using stock OBDII and it is not adjustable 'on the fly' but must be done with a laptop. I suppose it's failsafe is some sort of map switch or modulation but I have little idea how to trigger that. Last edited by Kapt. Q; 20-01-2013 at 09:33 PM. |

Re: Smart injection
Hi Dust,
Good link, he was going to use the washer bottle, but it is not suitable as it is in the front. Space is a big issue, but if I mount something like the Howerton set up in the rear luggage area it will be within about 1 foot of the two injection points, significantly simplifying plumbing. The system Richard is putting together has two nozzles, pre turbo and post intercooler. I think he is aiming to have greater capacity than 20% of fuel flow possible, to allow for some experimenting with mix, etc. I think they have strict emissions in Japan that would make this project a non starter there? I have had many cars in the past, including Porsches, VW, Jeep SRT-8, Mitsubishi, etc, but few have made me smile so much as this one and the challenge of getting more out of less is perhaps more rewarding than making a big motor go quickly and quite relevant in these 'green' times, lol. Cheers! |

If I have to move back here we WILL be installing an aquamist something on a direct injection diesel, or direct injection kei-car. I'd already have a diesel smart if they were available in Japan. I have an HSV, FAV, fittings, and about 10 nozzles, and don't even have my kit yet. |
