Hello Aryan,
thanks for warm welcome!
And thank you very much for your interesting & detailed reply!
Hello Horst!
Thank you for yours

Ethanol related:
@Austria fuel stations:
thanks for maintaining this list (I've never seen/found before). All I found was this company, they should be opened in the next months:
http://www.superethanol.at/frontend/vie ... E=&TEMPID=Aha we will have to ad these, to the database, do you know anything about pricing? This summer we made a trip to northern-Italy (before the 2cv Worldmeeting) with the BX and GPS with the tankstations we did it solely on E85 with some planning and 2x 20l extra jerrycans we didn't have to tank any petrol, not even in Italy because we made at trip to France to fill her upp again
We passed triugh a corner of Austria too but went mostly through Schweiz because we could tank there.

@Your piggy back E85 adapter:
http://www.flexitune.se/ seems to be reasonable for ~50€. I came along this adapter to this forum and thougt this is juste the company support forum. I guess it's independent, isn't it?
Yes, the flexitune is indipendent, they sell a very nice DIY kit, if you managed to make the megasquirt this is a piece of cake!
ami8i skrev:
How does flexitune consider E85? I guess they just increase injection time at a given value of about 20-30% so that the OEM ECU can manage as nothing would be changed. At least I'd try that.
There is a potentiometer where you can multiply injector timing from 100 to 200%, it has a 3 settings wire connection: ground (=petrol) , +12V (ca E50), open circuit (E85), the "half" E50 setting is for something inbetween petrol and E85. It also has the possibility for extra fuel during cold starting on E85. BTW you would need 40% longer timing to get a propper amount of E85, but fuel consumption will increase with ca 30% because the engine will run a little bit more efficient.
ami8i skrev:
Can you give me some details about your 123 prototype converter? Price?
It calculates wheter there is E85 or anything else in the tank by using the lambda signal and changes the fuelinjection timing and coldstart enrichement accordingly and indicates on a display how much ethanol it thinks there is in the tank. It can work with low or high impedance injectors and calulate with the opening time of the injector. I still needs a temp sensor to make the cold starting temperature dependent and add a multiport version for sequential inj systems. Pricing is not ready yet .

@Fuel pressure:
I thought also about just to rise fuel pressure.
» Maybe I'd could control flow characteriscs of a common MPI fuel pump (2,5-3,5bar typically) by providing a PWM signal to consider various Ethanol rates (E85...E50...E00) in the tank.
» Since I use a BX16 tank I still use the OEM 1bar (SPI) inline pump. I thouhgt also to add another one in series, but I have no idea what happens if this second one is switched off --> is the OEM pump strong enough to pass the 'dead' pump?
How do you consider various Ethanol rates? Your pump will 'overflow' the injector if you have just ordinary fuel in tank.
With PWM and no pressure sensor you will not be able to get an constant pressure. If you have a fast pressure sensor a electronic pressure control system would be very nice but not ucomplicated to make.
Much easier is to just add an extra (adjustable) fuel pressure regulator in the return line raising the FP to 200% is neccesarry to get 40% more fuel. Malpassi is for example a good choice. With a bypass valve you can switch between original pressure and raised pressure..

@KDY engine modification:
Yes SPI KDY was the latest BX engine, even the wasted spark SPI KDX (AX) was never introduced in BX.
I see!
ami8i skrev:
As my signature says I raised up compression ratio to 10.3:1 by removing 1.0mm (cylinder head gasket leaked). How much did you remove to get this amazing compression rate of 12.5:1? Did you grind the pistons not to touch the valves? An Austrian AX tuning guy would be very interested about your mods! Maybe you could post/send some pics (<250kB> GB, D
Thank you for the Systran Swedish include link!
I, don't remember exactly how much it was, I think al little over 2 mm, I simply took as much as possible as you can see I should have taken out the valves before
The stock belt is now almost too long and of cause the valve timing became a little later but not too much.

@KDY ECU diagnosis socket:
I removed cooling temperature sensor, idle stepper motor, TPS.
Strange, that should give you error codes 14, 21 and 33 !

@Long MA gear box:
If I'd change, I'd like to change to a newer TU engine, the AX gear box is rather nice to drive.
Thank you for the warning that newer gearboxes/TU engines are not plug&play-able.
Search on a Peugeot 206 forum if you want to know exactly.
ami8i skrev:
I got my AX Diesel box by this guy 'Luc' who has another one to sale (very chaep!)
http://51079.homepagemodules.de/t13f7-a ... enken.htmlMaybe it's worth to pass by
http://www.hermespaketshop.at/ which is much cheaper than common delivery services.
Hmm that sounds really very intresting, Thank you for that tip, I need to replace the clutch anyway, so I could just as well replace the gearbox as well!
ami8i skrev:
The speedometer is wrong so I built in a bike tripmaster Sigma MC8 (~18€) with 2 magnets on the left drive shaft --> I see speed up to 150km/h.
I bought a VSS pick up of Pug 106 to feed a DIY bord computer one day, because I WANT to know current fuel consumption to select the optimal gear!
What is a VSS pickup? With a duty cycle instrument that show the percentage of time where the injector is open you could do compairative fuel consumption if you know the engine speed..

@BX14Break:
Was just sold in Italy and Greece, also they could buy a BX11 (Sedan only). In Austria the BX14 Break was just registered by Citroen Austria in 1990 but never offered by dealers. The registration statistics told me that 4 BX14 Breaks were on the road 2 years ago, last year 2.
I got the papers from citroen Austria so I'll legalize the conversion soon (minor things are to do to pass the 'strong view' of the MOT officer).
My car was a BX16 break TGI (model1992), I changed to TU (KDY iron cast) eqiupment but saved the steering assitance
http://www.bxig.net/profilepic.php?u=728&fullNice gimmicks like 4 electric window opener , IR remote control central locking, 3(!) head rests rear, 2 long(!) head rests front, 5 floor interior lights...
A lot left to read.. I could get a nice BX19 break for free but converting it to BX14 would be quite complicated here with the paperwork, nice that you could get teh papers from Citroen Austria!
Would be even more intresting to make an BX with ethanol optimized lean and mean turbo compressed 1,0 AX/205 engine

@2CV world meeting:
No I wasn't there. Just 1996(?) with Dyane Caban in SLO and 2001 in A (but as helping hand --> Ami parked in seperated area).
My dream was to modify transmission ratio of GSA 5 speed box for the weak Visa engine and fit into the 2 cylinder frame to pass the long distance to S with low noise and low fuel consumption.
@My current NEW gear box in Ami8:
But I managed just to fit step1: a LN gear box with bigger GSA disc brakes. I use/organize this adapter plates
http://megasquirt-de.serviceline.ch/suc ... er0001.htmI have also a set of Olcit/Axel brakes on the shelf...
Hmm a lot to read later, thanks!
The original dyane gearbox is not to bad in a not so earodynamic acadiane... But I have a LNA gearbox laying arount which I'd like to experient a little with. Biggest problem is that the first exhaust under the gearbox will not fit?

@Ami8 conversion:
The link of my documentantion is in my profile. I use EDIS ignition module and MegaSquirt as Controller for EFI and ignition. Sorry for German 'lyrics' but there are many pics so you'll get a feeling what I have done.
Next projects are to rise compression rate and twin spark: Either by using 9.5 pistons (V06/644) or doing it on the millinmg machine.
One cylinder head is nearly finished need just time to swap.
My 2nd hand metal cats are made by Hubert Meyer
http://entenmeyer.de in Germany (designed for 2CV in heat exchangers --> improved heating power!)
»Horst
I have a set of new VISA cylinders (and 9:1 pisons) which I will raise compression by taken something off, a friend has already done that. Btw the pistons are very heavvy, I wonder if these couldn't be made lighter. At least I'm planning to carefully make them weight balanced.
What performance improvement/fuel consumption decrease did you get with the megasquirt? 123igntion is working on a bolt on carburettor replacement with monopoin injection.
Kind regards
Aryan
