Hi

I am changing my green injectors (stage 3 ) to light blue ones and fitting a 044 pump at the same time , now would i be able to do this and then drive my car after it ? as in to get it set up ?

Basically need to know if it will do any harm between fitting them and a 20 min drive to my local rolling road plae for setting up


thanks

 

DONT think it will run(well enogh to drive)due to the chip NOT being right for the light blues!

 

will be cool rab..just dont rag it

 

 

could bore wash like mad from cold especially (15% more fuel at cold anyway,plus whatever the difference is between light blues and greens)

changing injectors takes like 2 mins anyway,you may aswell wait til you get to your tuners (unless your selling the greens to pay for the blues)

 

it could do some lovely harm!

 

I'd be tempted to change them when I get there.

 

thats what i done rab,just changed injectors,map sensor and chip when i was at ava

 

I was hoping someone would bring this topic up.

I did this same thing a few weeks ago... During the process of setting my car up with a new MSD closed loop chip (stage 3, greens) I decided to try a set of light blues I had from a previous project. I was also told the car would over fuel but since I still have my greens I figured no big deal I can always swap them out again. Well to to my surprise after installing the light blues and resetting the CO the air/fuel is still pretty decent with readings in the 11.4-11.8 range at full (24psi) boost. So for now I'll leave them in, I like having the additional flow capacity.

Another for Stu's closed loop chip.

 

svony

your getting a af of 11.4 where it is ment to be 12.2 when it was mapped! your loosing power!

bad advice i would say

 

Gareth,

Isnt 12.2 a little on the lean side? I thought 11.5:1 was ideal for turbo'd cars?

 

I dont believe stu would intend an off the shelf chip to run 12.2 either TBH

Seems "risky" to me, and stu doesnt seem the sort to take risks!

 

Going back to the original question..........


Rabmc, you do realise your local rolling road will have to change the chip to get it running correctly?
They cant just magicly change a couple of settings.

Unless they are able to remap the chips themselves?

 

ditto chip, you need a new chip anyway

and svoney, it sounds like youre ill informed on how chips and injectors work. you NEED to run the correct injectors, and you don't just have "extra capacity"

 

i know,, but stu must map it leaner than 11.4 though it was just an example

 

exactly.

if your injectors are mapped to provide x amount of fuel at y rpm, then no matter what injector, if it uses the same voltage, it'll still the same. if its a different voltage, you may get less or more fuel.

doesnt mean its any safer!

 

Different pulse width rather than voltage, but yes thats correct.


The closed loop will manage to correct it off boost though if its fairly close still.

 

cheers chip, did wonder, but i was talking to a mancunian at the time of typing this, with visions of Fraggles and Muppets in my head

 

ummmm, ok

 

Ok guys here's the deal... The chip I have was bought second hand for a car in the UK, as such the map is for your higher octane fuels. I'm in the states and all it takes is a bad tank of premium (91-93 octane) and there goes my motor, so running a bit rich for the sake of a few BHPs is fine with me. I have been able to lean the air fuel out to 12.0 by reducing the fuel pressure (2 pounds). I just chose to run it rich for safety.

I'm still debating wether or not to reinstall the greens or keeping the light blues as the car runs fine with either but I obviously can richen it more with the blues, plus I have a ported head and intake I need to install.

Hopefully Stu will chime in here but I think Chip is on the right track.

Thanks for the input guys.

 

Rab where are you getting a chip from for the light blues?
i had bother a few years back with the escort when changing from greens
to ice blues as said above better to change them & the chip at ava ect...

 

It was a random conversation.

 

svony, i can see why you think what you do, but unfortunately you are wrong and playing a very risky game!

yuo need to get no the phone to a reputable UK supplier who can send you a chip for your spec/fuel

as for short term? refit the greens.

as for your shonky fuel. your octane rating isnt in RON like ours, so 91octane doesne mean 91RON

 

Right guys my email thingy must not been working and didnt realise this was still floating about ?

Now good reading and learning for me , going to get a suitable chip for my spec from motorsport developments hopefuly

What kind of prices roughly am i looking at for a chip for my 3 door L1 ecu

Going to phone them in a bit anyway as my blues arn`t here yet

 

I have no problem refitting the greens and will do so this weekend but I'm not clear as to what issues I would have with the light blues that has not come up as yet?
If anyone has the Innovate wideband monitor I can send you my air/fuel logs to look at. Obviouly I'm no expert but looking over the logs I can't see anything in regards to air/fuel ratio under boost, part throttle or otherwise that looks out of the ordinary.

I'm not thick just trying to understand what to look for or expect from such a combo, maybe I can help someone else attempting to try the same thing in th future.
