Which model of B230 was the block?

You're on stock GLT LE-Jet and Renix, right? I'll buy you a beer if that isn't your problem...
I reckon if you stick it on a dyno you'll find you're running lean up-top.

You've got two options:
# Programmable EMS (Megasquirt is the cheapest option, but requires a little DIY....doesn't sound like that'll be a problem to you...)
# The EMS setup from a 940, with lambda. LH-Jet 2.4 is much more forgiving of alterations to the engine spec.

The 2ltr system in good nick sould run a 2.3 ok. I have done this in the past in a 240. It did run well and gave good mpg. The easy answer is it put lpg on it My way around any problem

Easy for you to say...
I am going to install LPG in mine aswell... but it will cost me €1000,-
It will pay back itself eventually considering the insane fuel prizes here...
€1,40/l euro 95... fortunately LPG sells for €0,40...

Is LPG liquid or gas?

Why in here nowone sells it, or even no news from it - Shitty goverment, I guess.

Diesel is cheapest fuel in here, 1.0x euros/litre.

Hmm, is LPG Liquid Gas? Something like that I heard, I think here is one station for that in whole country and only city buses uses it. Perhaps it was in Helsinki (300km from here).

Of course diesel cars get extra tax that is needed to pay every year, 0,63 euros per every beginning 100kg, and for electric and other than gasoline cars that is bit higher... Kill's whole idea, I think.

Unless it was a very late 240, it'd have had K-Jet mechanical injection, right? Mechanical, and electronic with lambda are forgiving....mapped injection without lambda (ala 360 GLT....part from Aymat's!) isn't...

LPG Info
It is Liquified Petrolium Gas.
Cars with LPG installed do get a fairly high tax but with the fuel consumption of a 360 it is worth it.
It takes me 3/4 year to earn it back.
After that my monthly running costs will be cut in half.

Ok, thx from info and link

I could be wrong, but didn't it stand for Liquified Propane Gas??

Ehhh true... my bad...

The best think about lpg (excluding price) is you can run very high C/R without pinking!! LPG has a high octane rating about 105 if I remember correctly.

Dai

Now that is cool - race fuel is only ~110 octane. You could have turbocharged fun on the cheap there too

cheers

James

No pinking indeed... but slightly higher temperatures...
I think I might just add a turbo and IC... mayby install an Aquamist system to cope with the higher temperatures...

Hi again guys.
I would just make a slight update about my problmes.
I will try out some adjustments on the AFM in the weekend.
I have talked to some Opel tuners who has been making a lot of adjustments on these AFM's and they said that I would be able to tune the system by making adjustments on the AFM.
I will try it out this weekend and se how it goes.

regards.
Peter

IIRC the AFM features a master mixture screw - that might well help you. You really need a diagnostic run on a dyno to tell you exactly what's going on, allow you to set the mixture accurately whilst under load, and determine whether or not the AFM adjustment will be enough...it ought to cost...~£50?

cheers

Hi mate, I take it your car has the 'flap' type airflow meter? If it does, pop the lid off the meter, inside you will see the spring that holds the flap shut. it is mounted on a wheel with teeth round the outside, you can rotate this wheel to adjust the mixture under light load, and from the sound of your post you need to richen it up, try removing 4 'clicks' of tension and re test. (releasing tension richens the mixture, adding tension leans it off) you will find little or no effect at full throttle, as the throttle switch has a full load contact inside to tell the ecu you have floored the throttle, and it will trigger full load enrichment and ignore to a large extent what the air flow meter is doing. What size were the stock injectors, and could you post the figures from the wideband? I may be able to help as it is what I do for a living
