Whats the ideal afr reading on a cossie under load? my car is running 13.4 is that too lean

 

Aye mate... Stus the man to tell you but im sure 11.4 to 11.7 is ideal flat out.

 

what ollie said to be safe usually under 12 so 13.4 is dreadfull if thats flatout in the boost cycle

 

Fuck looks like my car wont be coming home 2 night

 

has it got the new engine in now mate?

 

Yeah mate new engine is in , car is looking good just need to get it running a bit richer i have dropped the fuel pump rewire loom at andrews he will fit it during the week im off on holiday 2 moro.If that fails andrew will get a chip & set of greys from harvey.

 

Mine is 11.7 flat out carlo,MSD chip on blacks.

 

Because the low comp 6.8 i spoke to someone at msd they said it needed live mapped which isnt a option for me.I have no holidays left this year & would need a few days either way to take it & collect it

 

fucking way to lean high 11s you need

 

Carlo,

Whats it fuelling like else where?

If you up the fuel pressure to richen it up on boost does it run rich as a pig else where?

 

On the plus side, if its leaner than it was before you added parts it means its flowing more air and you should be able to make more power!

 

be good to get it to msd and get it set up properly.why the hell did they have to be so far away

 

it was 13.8 at 3.5 bar upped it to 4 bar & went to 13.4 also reset the ecu screw.Im hoping its the fuel pump wiring but not too sure as andrew said the pressure is still ok on load. its on seimens blacks.When he puts the rewire kit on if its still the same i will get a low comp chip from harvey & greys see how it gets on then

 

kind of repeated myself above there lol
& stevie i know they are too far away

 

What pump you got?

What setup is the chip you have in it supposed to be for?

 

Only a couple of hours down the road m8,well worth it,my car runs superb now.

 

mines 11.4 flat out. your problem is mate its flowing much more air than your old engine. its an awesome spec engine youve got there . get it live mapped mate you dont wana melt it itl cost a fortune if you do.

 

That new engine time lean - be careful!

 

O44 pump new fuel filter . chip is a NMS one to be fair to karl i did give him the spec over the phone so it it dosent to its my fault as he did warn me.
I spoke to karl today he ws very helpfull top bloke.By the time andy got back onto the car i couldnt get a hold of karl to let him know the results.But karl reckoned the fuel pump rewire kit was the root of all trouble as it was wasnt fitted

 

The car wont be driven if i cant get the afr better so it wont be getting melted..
Live mapping is prob the only solution but every fucker is miles away as said before i dont have days off work to travel.
I dont want to buy another ecu & get ava to map it as i will get fed up with the car by the time they are bye with it

 

Sounds like unless the re-wire works you need to get the chip re written.

If you give Karl some afr figures he should be able to work out how much fuel needs adding and just scale up the on boost section of the map.

 

carl there is nothing on my engine that was on the old engine, new ryan loom,chip,injectors ,engine sensors everything is new.

 

well i cruise at 15 afr, very unlikely youl melt it off boost mate.

 

Doug thats a option i will speak with karl again , trouble is im going on holiday 2 moro for a week the car is still at andrews so i wont know the results for a week.
This was only at 25psi as well

 

most likely is prob chip then mate was chip supplier told exact spec carlo ?

 

Yeah mate he was told but i was also told that it would not be ideal the responsability is on me totally karl has been sound.

 

t4 it buddy you know it makes sense.....ha gies a shout when you get bak mate,

 

Will do col would love the car to be right before i even think about a t4

 

sure it will be fine carlo,strong engine youve got now mate,just need to get the map sorted

 

Carlo.

You will be plenty safe to drive it home cautiously. Set the boost as low as it will go. 7psi ish and then drive her home. Don't use more than half throttle but do drive it a bit so as not to glaze the bores.

 

No point taking it home doug untill its right tho may as well keep it at andrews untill its sorted

 

pmsl @ blacks......

 

all the quotes of msd - stu might be very good but i have never been in a fast car he has mapped - so please go to a tuner based on your expectation.

Fast car or one that does 20+ to the gallon LOL

 

Thats right Dingy... a black smoking, over fueling piece of shit is always faster.

Do you know anything about mapping?

 

Dingy please dont let this thread turn to shit , im only after a bit of advise & a few opinions.I would love stu to comment on this thread & give his opinion on what im asking

 

Why's that funny m8 ?

 

my car was originally mapped by nms and i had it redone by msd as i wasnt happy with it. surging its tits off. and its faster now than it was before and better on fuel.

what cars have you been in that stus mapped then ?

 

Buckle up ppl

 

As said above Carlo get the afr readings at set rev and boost points to give to Karl and he will beable to mod your chip. If you do end up with a Harvey low comp chip give me a shout and i will check with ava that my greys are still there.

 

Will do neil i have left it up to andy to do what he needs to do i just want the car running ok
