cossy pinking at 1.8 bar but when turned down to 1.5 bar no pinking its running greens and was mapped for super unl. and no its not my cossy its a m8s one this only happens when he uses 95 ron fuel but when using 97 ron fuel you can just about here it but its ther any ideas as to what it can be apart from the chip

 

was it mapped for 1.8 bar?

 

IMO ANY Cossie, esp one running nearly 2 bar, would ALWAYS need to use super...

my rs, running 0.7bar, pinks with crappy premium

maybe the reason?

if not, timing?


dre

 

just reread,, if it was mapped on super,, whats he doing running it on a lower ron

 

kaboom on the way

 

Agree with this


Some people

 

GARETH T, it was not maped for 1.8 bar and dont realy no why he is runing non super unleaded pure stupid ive turned the boost down and thats that iam not getting involved just in case it goes tits up

 

 

 

HES ONE PINKING REALLY BAD

 

abbs you have just answered ya own question mate

all cossies need to run super, tbh they really really need leaded 4 star but that aitn gonna happen

if its not mapped for the boost then its not gonna have the fuel map there, greens run lean on a cossie with a t34 at 1.73bar, well mine does anyway, thats on optimax and at 6000rpm under load

running normal fuel will make it pink, thats why ya use super as it stops the pinking

tell ya mate that even though his car will be sooooooooo much better for throttle responce and power what is actually happening is hes cylinders are getting soo hot that the fuel is sparking from the tip of the plug and the temps of the engine BEFORE the spark

thats when the cossie engine melts

i know ya get a hard time on here, its hard work for lots of people tbh, but in the end people like gareth ect do know what there talking about and they do mean well

so to recap, he needs optimax, fresh optimax too as it goes off after a month ive noticed and also run the correct boost for the map, anymore OR any less and the car will either melt or dilute the oil with fuel

 

please take this down as if the missus sees it shes gonna make me get the cossie sprayed that colour

 

...except the lambda/cat equipped ones

 

yeah they need breaking for spares , why buy a tree huging aproved sports car

when i driove the cossie i want to get out on the coldest winter morning, turn the key and recive my hose pipe ban from the council on my way to work

 

LOL, but just didn't want anyone to poison their cat's or lambda sensors

Other than that, I agree with you re: SUL and Optimax compared to 95RON in Cossies (or RST's for that matter as quite a lot of people thought they came 95RON capable from the factory when it was actually 97RON).

 

dont agree with me, it was abbs who spotted the problem

i had top PM ima for the answer

 

ffs is this a trick question

ps, any cossie could run 95 octane if it was mapped for it, bit pointless with the amount of advance you would have to take out, but it could

 

Some good advice....

1) turn the boost down before it melts.

2) DONT EVER run it on 95ron unless it was LIVE mapped for it


Dark greens under ANY state of tune should NEVER hold more than 1.5 bar above 4200 rpm as the injector duty cycle is on the limit if not over it at that boost.
I.E LEAN !!!!

 

mine aint,,,,,,,, well not untill 6k it aint

dont ask about pops

 

My advice was based on the average cossie as a general rule.
Factors such as fuel pressure differences, head skim, valve seal quality, comp ratio, cams etc...
ALL have bearing on the limits too.

Cars that PUSH the limits can gain and be safe IF live mapped and tested at the limits.

 

i just turned me bleed valve and me mate kev said it was fueling fine as when he was following me it was still flaming

 

nor's mine ginge, 6k it drops to 21 psi
lucky its well over 2 bar before that

 

popsya going to ford fair as if soo need to borrow ya skills for advice

 

a big thanks to b19bal for that good advice and a thank you to SECS also gareth t for lending some advice to top people

 

FOOK ME, gine has had a thank you for some advise

and what would that be AL?

 

im only giving good advice as ive just realised who ya are

small world aint it

 

get on MSN then ( or unblock me )

its not a long bit of advice but its deffo needed with some help from you

 

b19bal, i still dont know how you are m8

 

i know, thats why i aint told ya yet
