im going to be changing my grey injectors to either siemens,or rc not sure if i need to go as large as 1000cc but my greys are getting maxed now

also im getting a 4x4 head ive got ported and polished,thinking of going 27 on inlet and 25 on exhaust,and a 4x4 plenum matched to it(poss an ava sweedish type inlet made up)

is it safe to assume il need to send my chip back to be re written mate?

 

ever wish you had went for a prgramable system col?

how many chips now?

 

i would say that you would mate

 

Any change to VE will require remap

JJ

 

ive only bought the one thats in it now euan

the other 1 came in the boxes with the car,sold that 1

i might still go for a mappable managment euan,still waiting to see how neil gets on with the collins 1,cause im defo no spending £3000 on one of the others +the money ive saved in fuel on long runs with the closed loop should pay for sending chip back.....

 

up

 

my mistake col, i thought you were on your 3rd one or something

really a case of doing the mods then getting it checked on the rollers for det aint it

 

cool just want to see whats stu`s views are on this too

 

That really has to be the most stupid coment on the thread. Certainly not worth the risk imo.

 

how is it stupid? I said get it checked for det in a controlled situation by a pro...
whats silly abou that?

 

Sorry if iv read something wrong but shouldn't the checking go on AFR to prevent det, not to see if it actualy does it?

 

AFR wont tell you if the ignition is out though

JJ

 

am i missing something here?you already have mappable management dont you?

 

what AFR does det occur then?

just beacuase a car is at a certain AFR you dont know if its detting or not unless you listen for it.

 

According to Stus thread there is no set AFR that det occurs and it could be different for each engine if i read that correctly.

Few of these for me for being a thick cunt and not even thinking of ignition timing either, so sorry Euan for the above comment.

Right im off to go and learn on how to prevent det

 

no worries mate, Im no expert either

 

surely it would be better to phone stu or pm him regarding this ?

 

I was thinking similar as at least you will get ONE proper answer that is correct rather than lots of guessers.

However the answer is yes. Changing your spec so dramatically, injectors, head etc will require a totally fresh chip.

 

and its £250 to have it rewritten,so im just going to sell it and my ecu i think

if i mod my car further in future its going to cost me £250 a time to have the chip changed

 

Col atleast Stu now does off the shelf or self fit chips for bigger spec cars , when i decided to go for the Collins ecu you had to take anything with greys or above down for a week for a live map realy.

 

yeah i know neil,ive had no probs with the way my msd chip works with my engine on an off the shelf job but with upgrading im a bit like do i really want to spend another £250-on a chip ive already paid £350 for know what i mean,when i could get a mappable management for 1k and sell chip and ecu for £500
