.....i wouldn recommend cf over 3

Upto 6 cf's are what people class as .acceptble'.

 

[jonnyblease]

il aim for that then, i can't see plugs and fuel reducing the CFs much more than that.

I wonder how long its had such high CFs make me worry a little as i do like to give it some spirited driving when the oppertunity arises. I really dont want a piston melting on me as i couldn't afford to fix that kind of thing for a long time.

True say but in hotter days that will rise back up
winter here so you want to keep it low as possible espically with smic.

So guys,is the general opinion that BP ultimate is crap
Its all i've ever put in mine as there is no V-power in the county,what's the next best fuel then?
BTW apologies jonny if i've hijacked this thread a touch,just I have same kind of issues with my logs as yourself,and the comments about fuel have me thinking

well when i was searching on this forum to find some solutions on timing pull i read that on remapped cars the fuel needed is usually 98/99 ron and BP ultimate is 97 so its not really adequate.

However i didn't think it would make that much difference you could always just bang a little ocatane booster in maybe half a bottle to higher the ron a little.

Clear all fault codes and do a throttle body alignment. You might still be running some built up adaptions from when you had a dead maf.

Do all those and re-log 020, everything else looks fine.

Also, dont bother with 032 and 031, we have a narrowband lambda so those figures are next to usless when logging.

I have cleared all the fault codes, i did think i caould be running some adaptions from a previous dead maf, i may reset the ecu.

Noob question but 'how do i reallign the TB'?

thanks again

btw i have order some NGK BKR7s and will fit them over the weekend.

Turn the key on but do not start the car.

[Select]
[01 - Engine]
[Measuring Blocks - 08]
Group 060
[Go!]
[Switch to basic settings]
Once you do this you will see the top right display say ADP RUN. The TB adaptation is being done as soon as you switch to basic settings. You will see the values change and hear the TB cycle for the first few seconds then it will stop. Leave it in Basic Settings for about 30 seconds.
[Switch to Meas. Blocks] button and you're all set.

Be sure not to touch the accelerator and make sure the engine is NOT running when you do this!

Can/does this effect a re-map, ie remove it and return the ECU to standard?

 

[james walker]

definatly not mate.

Just to ask, what blocks would you then recommend to measure the fueling is right?

 

[james walker]

maybe have a ready of this.. explains fuel trims/air mass etc
