Hi, I have just been given a JWT chip by my son who bought it from the forum, question is, I have spoken to a firm about soldering a socket into the ECU, and they say with this chip the boost is upgraded WITHOUT any controller or boost mig tips ect. He expects about 14 psi from it. Is this right?

Doesn't sound right to me. I would have thought the generic fueling maps would have been changed to allow extra boost safely.

No

Thanks, thats what I thought, so does this mean he is a Wa**ker? I wonder.

yes mate .. he is a complete :xxx:

Not necessarily, but it does make him wrong though. ;)

 

I'd be interested to hear his explanation of how the chip manages to increase the boost level on its own without using a mechanical solution too...

John Dixon can socket it for you, or Ryan (Baggins).

Not necessarily, but it does make him wrong though. ;)

 

 

Yep ... I retract my last statement ... LOL

No Chip will give you 14psi of boost the boost is not dictated by the ECU in fact the ECU has no idea what boost you are running at all , there are some chips for example MINES that will make the car a little quicker but this is all down to leaning fuel out and optimising/raising timing at certain load sites

 

Ryan

OK, I think I might use him to socket it, only becasue he is local, and he does do this type of work. He wants £40.00 to do it, inc removing the ecu from the car and making sure it runs OK afterwards. Does this sound about right? I would like to use someone form here but are they local to me? Buckinghamshire. And, when its done, what size migs tips shall I start with? I dont want an unreliable car just a bit extra, I was thinking 12 to 13 ish? As in PSI. On the JWT site it shows a manual boost controller as well as restrictors, I ask because I dont see how a restrictor cuts down presure, sure it will slow it down but it will get to the same sooner or later.

Yeah but when the stock boost solenoids open they open up a T-piece with a bleed valve in it ;)

I see, thanks for that, I understand now.

What size jets shall I start with?

1.2mm is a good starting point. make sure youve got a decent aftermarket boost gauge tho

I am nicking my sons boost gauge, he doesnt know yet. Thanks everyone.
