How can i check to see if my ECU is chipped ?
I have just opened it & there is a long brown chip
with a clear circle in the middle of it with some
black marker pen writing, but i cant tell what it
says. Does it sound standard ?

 

What car is it?

Doesn't sound standard as most chips I've seen have a barcode or serial number on the back.

If its got marker pen on it, I'd say it was a fair bet that its aftermarket!

(fook knows whats in it though!)

 

sorry mate its for a s1

 

I just fitted it and it fooks along spins in 3rd gear now

but my boost gage only shows 0.5 bar

not sure if gage works proper or not

on idle it shows -1 bar

 

Beware of over boosting if it spins in 3rd! Fook me!

 

o.k its dead now
it feels like it is holding back at 4k
it really struggles under load

 

that could be your ecu saying fuck off what u doing and cuttin out the boost

 

Thought it sounding like too much!

What engine spec are you on!

If you reply standard prepare for me to do this

 

its got a KnN full stainless -31 act samcos and thats it

 

and the car has only done 32k from new

 

by the way the ECU is a hearts and diamonds

 

Hopefully it was the ECU saying 'NO WAY!'

Or you may have melted something!

 

just took her out again boosts well again
& then it stops again its like the actuator
rod has fell off

 

oh bythe way the circlip thing that holds the rod
to the wastegate lever has come off
has any one got a spare 1

 

You can wire wrap it to hold it in place until you get a new one!

 

i never even thought of that

 

sounds like someones engines going to go boom

 

hope not

 

o.k it wont boost at all it cuts out
what could it be?

 

air leak

 

cant find 1 at all

 

maybe fuel starvation but it sounds like a leak to me

 

its like hitting a wall just dies
somtimes it will pick up

 

what plug gap should it be?
i just had new plugs fitted

 

25 thou i think dont qoute me though think it deoends on your bhp etc

 

o.k i will try it in the morning
CheeRS

 

you got any pics of it mate

 

no sorry i asked my brother to sort it but
hes a LAZY SHIT

 

Shall i refit my standard ECU and try it?

 

could do mate

 

right i have been playing today all 4 gaps were
massive 1 plug was loose and another was cracked
drives alright now but only hits 0.3 bar

 

if i were you, i would set everything back to standard, and run it like that for a bit to gain a bit of reliability/trust in the car, and then when you feel it is reliable have it tuned.

 

Id put the standard ECU back in before your engine ends up doing this





It's not a good idea to just put a chipped ECU in and turn the boost up if you have not had it rolling roaded/tuned so the fueling is right.

 

I have a spare 1900 for it i just wanted to
see what the 1600 will do the car and lump
has only done 30 k so should be a nice lump
Back to standard she goes

 

is this not an s2 ECU, dont think an s1 will run properly on it.

 

it is a S2 ECU runs fine now
1 bar of boost now
shes nippy

 

All ECU's will work on any RST loom but if you fit a S2 ecu to an S1 it needs the knock sensor connecting otherwise it majorly retards the ignition.

A BAR you said 0.6 in the PM!! Your guna make that thing go bang mate i did say dont get adjusting the actuator too much

Don't come crying when it goes bang

 

yeah we turned it up but then we turned it back down again
