My car is nearly leaning out. If I want more boost I need to...

If you ever need it re-tuned for mods feel free to pop down to melbourne and I'll give you a pretty good discount on dyno time.

Thanks SydneyKid - any recommendations?

Thanks Dr - hehe I don't know if that would be offset by the petrol and time spent getting to and from (i work a pleb 9-5 mon fri work so not quite feasible). Thanks anyway though.

I was actually wondering how to put the same tune from the current ECU and put it on a PFC as a base to start tuning it in Sydney. Is that possible? (i'm talkin many many months down the track here).

Thats not leaning out!!

This is :headbang:

[someonestolecc]

Fuuarrrk.

Did that engine survive that?

[Dr_Drift]

someonestolecc - I love tuning that car... I'm sure i can make it feasable... we're open weekends also.... As for converting to pfc, no chance, completely different storage methods...

[someonestolecc]

Sweet as.

Thanks for your help dr. No doubt I'll be contacting you soon for some more questions.

I just gotta get some niggling things ironed out and she'll be ready for some upgrades etc

Fuuarrrk.

For general Intrest, No that car didn't survive, As it was running stock fuel pump, stock internals, stock ecu, and 13psi BOOST !!!!

Lol.

I assume the aim was to blow it up? ...orr.....?

I'm thinking of getting some larger injectors also after reading up some setups that also run this turbo at the power levels I'd like to have - but mostly for safetys sake.

My theory is if a 550cc has a clog, it flows less then say a 760 with a clog..

My further question is with larger injectors that aren't flowing more? (ie they're just larger but not pumping more fuel in on that map) will it affect fuel economy? and is my theory that larger injectors would have an easier time with flowing fuel whilst being clogged?

I'm 50/50 thinking this at the moment cos on the other hand I guess the injector is just capable of flowing more - if it's not flowing more then if it gets clogged flowing 400cc (say) equivalent of fuel then it don't matter how big it is it's still blocking 400cc worth of flow.... if that makes sense.

Yes that was the aim, It is now our Project Car :-)

As for your injector question ? Is it me or did that not make any sense... ??

[someonestolecc]

Well.. I'll re-phrase simply with (a theoretical) assertion as the 'spark'/stimulus.

"550cc injectors clogged with 1 unit worth of gunk perform worse than 760cc injectors clogged with the same 1 unit worth of gunk."

"Therefore based on that assumption bigger injectors are more reliable even though the 550's are not maxed at the power the car is making."

--OR--

'If the injectors are flowing say 300cc at any given moment - whether they are rated at 550 or 760 they are both going to have the same trouble if the same 1 unit of gunk clogs them."

[Cubes]

The point is if a car is tuned with a 12:1 AFM and an injector becomes clogged then that injector is going supply less fuel in turn leaning out. It doesn't matter if the injector is a 1000cc, if its tune at 400hp then it will still lean out. UNLESS you were running a wideband O2 sensor with some fandangled ECU that kept the fuel afr perfect.

[someonestolecc]

That answers my question to a tea - thank you.

Which basically means since the 550's are not maxed out I won't be upgrading the injectors. I will however be making sure they are not blocked!

Thanks again.
