Here\'s the pic of the car. I was looking at the chips on Ebay. I wasn\'t sure about them but if you have one and it runs well then I may just order one. I have a spare ecu so I can have a go at it myself.

The chip I got was ebay number 170184726338. The car seems to run fine with it in and the boost limit / fuel cut I was hitting before has gone. I\'m yet to find the rev limiter:2eek. The hot tickover did need adjusting. If I remember right I had to wind in the bypass screw near the filter before the idle screw near the inlet came into \'range\'. It passed its MOT last week with 2.5CO and 800HC, happy with that:Giggle. The hardest part of the chip swap is getting the old one out as I no longer have access to a Pace solder station. So you might want to make sure you can get it out of your spare ECU OK before ordering.
Does your car hit the boost limit then? Or do you have an FCD fitted? Mine was cutting all the time just with its decat exhaust and induction kit.

Do you know if the chips control timing at all ?
 
1 Bar is a lot to throw at the FC - can\'t remember if you changed the intercooler or not - if you didn\'t your intake temps are going to be quite high ! :2eek

No im running a FCD, it was on the car when I got it. But with the mods I have I should be running a FD fuel pump and a chip or remapped ecu. I haven\'t hit the rev limiter either and its been well above 7k in the past.

Prof,
I\'ve no idea if it\'s controlling the timing or not. It\'s on the std intercooler still as the budget\'s blown!! I did clean it out so it should be working as well as it can at least. I\'ve backed it off to about 12/13 psi now, but it seemed to be boosting at that without the MBC fitted :confused:. Either way, the boost seems to tail off to 8/10 psi when it is pulling over 5krpm. Is this normal? Or might I have a leak or turbo problem?
Cheers,
Nick

When you fitted the MBC, did you disconnect the stock boost solenoid - it tends not to do much when you\'ve chipped the ECU, and if it\'s connected it will probably be the cause of the boost drop off.
 
There\'s a good article about boost and boost creep on the 1300cc.com site - http://www.1300cc.com/howto/how2/creep.htm - will probably help explain it better than I can.

Cheers Prof,
I\'m just getting Gateway Timeout on that link, I\'ll try again later. Can you please confirm which is the Boost Solenoid?
Cheers,

Mine has a blue connector plug and sits on the oil filler neck - if you follow the pipe back that \'Tees\' off the small pipe on the turbo compressor housing, the other end of that is fed from the stock Boost Solenoid.  It\'s designed to bleed some air away from the wastegate, preventing it from opening until later, but the solenoid can be erratic and also can leak.  If you just pinch off that pipe near the turbo, you\'d be running on spring boost only on a stock car, but with intake and exhaust mods that would have risen to the 8psi that the solenoid gives you in any case.  More than likely it\'s leaking boost away.

Thanks again Prof. I think I\'ve located it on a diagram, the duty solenoid valve (turbo boost pressure control) sound about right? So if I pull the wires and the boost still drops off then pull the pipe and blank it off?
I plumbed in the MBC below the tee, next to the actuator. I guess if I\'d done it above then I wouldn\'t have this issue?
Cheers,
Nick
