You can try one from K-Jetronic systems (VW fox pump), people here used to use them on drag racing due it's high flow(nowdays they run with aeromotive), but I don't know how long it can deal with ethanol...

Maybe you can try one from Chevy Flexfuel trucks, I'm pretty shure that a pump that can ...

Hi,

Ethanol injectors are ~ 30 - 40% bigger than Gasoline injectors... About the steel tank, just clean it very well and you're good (ethanol takes all the dirt that gas don't). Make shure that you don't have rust on it...
You won't have any problems with plastic lines too.

Is your 914 engine air ...

Hi All,

Just made the calibration, seems to be a megatune issue ...
1 - Calibrate the IAT, it stops around entry 600, then restart MT and try again, it downloads all the 1024 entryies.
2 - Try to calibrate the CLT, it stops too, restart MT, and try again, downloads everything too.

Wierd, hunh ...

News :

Did a calibration with a real serial port, same thing... And yes, it was running at 115200 kbps, 8 pits, etc... no buffer.

I think that's a Megatune issue or something related to the MS-2 code, because, if i change the resistance value, it completes the calibration... I hope everything is ...

Hi Lance,

I forgot to write the values ... Here it is :

CLT

- 13C : 18,5k Ohms
37C : 1,6k Ohms
93C : 238 Ohms

IAT

-14C : 1960 ohms
38C : 1100 ohms
93C : 185 ohms

I'm running Megatune on a Acer Travelmate 2200 with Prolific USB adapter, no problems at all, can burn VE tables, ignition, etc ...

Hello All,

Just wired up everything today, calibrated the TPS without any problem, but when I try to calibrate the CLT / IAT sensors it doesn't work ! :(
When it says "Downloading entry xxx" it suddenly stops around entry 600 and doesn't change anything at all ...
BIAS resistors are 2490ohm, PCB ...

Hello Everybody,

I was thinking that the stoich AFR for gas is 14,7 (Lamda = 1 .. Duh !), but if you add 20% of ethanol on it, how would it be ?
And if you're using a lambda meter, such as LC-1, near the stoich point I think there's no problem, but as you put more fuel and makes the mixture richer ...

air mesure device must be AFM type, not MAP

it could be another AFM,
what AFM work with MS??

Yeap, it's possible to run with MAF with MSnS-Extra !

Take a look in http://megasquirt.sourceforge.net/extra/MAF_Stuff.htm

Good luck !

Just an idea...

Aren't you using too much gap on your spark plugs ?

Cheers

Thanks a lot mate !
