G40R MOT emisions

[ceebmoj]

Im having my G40R MOTed today and it seams to be failing on CO2. Looking back at the MOT history it seams to have failed on this in the past and then come in to speck. does any one have any advice for how to improve the CO2?

When I returned for a retest I passed the MOT. I had tightened the V band clamp.

I have seen a technical bulletin about the fuel pressure regulator being set incorrectly on some cars leadding to over fuelling could this contribute?

Hi James. The ECU for Zetec I think is different to Duratec, due to cable throttle instead of electrical throttle. You should find it somewhere under the left side of the dash. Power from 2.5 litre should be high 200's, maybe around 270 with the cams chosen for my engine. A lot also depends on the exhaust. The standard G40R manifold is only crude short branch plumbing and there is not much room to fit a full long branch tuned one. Engine job has been dragging on for a year or so due to problems with sump supply. I can see some light at the end of the tunnel now

Build thread please. I love my G40R and cant see anything else I want and can sensibly afford so an option to add anything like that much naturally aspirated power to the car would be amazing.

My 2.0 Duratec car has a traditional throttle cable and throttle position sensor.

Yours must be an early Duratec car, whereas mine is one of the last few they built. By that time the electronic throttle was standard.

Yep car no 2. I guess its another difference between the cars.

Do you know which ECU is fitted? Presumably it can be reprogrammed, the throttle pedal could be changed, and potentially the ECU may also support traction control?
