For what you’re trying to do, it might be easier to find a copy of the “Noble Dealer Diagnostic Software” - you should be able to find it out on the web. It should work right out of the box - no...

For high idle, and RPM undershoot on return-to-idle, the first things I’d check for are vacuum leaks. Second thing I’d check on a Rossion would be a contaminated MAF - you may want to remove the MAF...

I see you checked the voltage at the coils - have you checked the voltage at the fuel injectors, the crank sensor, cam sensor, TPS, and MAP sensor? Have you checked the fuses in the four-fuse block...

The controls and the heater valve are two separate things, accessed in different ways. The heater valve is easy - just remove the front tunnel vent panel underneath the car, push the hoses out of...

One thing to watch for - on the rear turbo, the coolant lines run above the rear exhaust manifold, then wrap around the frame rail and go down to the hard lines attached to the turbo. If you’re...

I’ve had to do this fix on several cars - I haven’t had to remove any of the riveted underbelly pans, just the screwed-on pan under the engine, and the rear tunnel vent. Once those are off, remove...

It’s fairly straightforward- the Bosch FPR is a 1:1 regulator, so the fuel pressure is maintained at 3 bar above whatever pressure/vacuum is present at the reference port. Since the reference port...

That red light is used for two things - first, it goes on if your brake fluid is low. Second, it goes on if your ebrake handle isn’t all the way down. From the factory, there isn’t a spring holding...

To get to the heater valve on a Noble, you have to come up from below the car. No need to drill any rivets or remove the floor pan. Just unscrew the forward vent panel and reach inside. It’s...

Nope, the M400s didn’t come from the factory with a front-mounted oil cooler either. They came stock with a single cooler mounted in the right side pod. Any Noble (M400 or M12) with an oil cooler...

Try tightening the nut on the bottom of the cap a little, like a quarter turn or so, to make it lock down a little tighter...

If you mean the bar on the bottom of the chassis, below the engine on the right side of the car, then that's the wrong bar. That bar is so that you can remove the oil pan without having to remove...

Ok, there are a few things in this thread that I'd like to clarify:

1. Setting fuel pressure. "Base" fuel pressure is set with the fuel pump on , and the vacuum/pressure reference disconnected...

No need to mess with the vacuum lines to disable the boost solenoid - just disconnect the electrical connector on the solenoid. With the solenoid disconnected, the boost will be limited to the...

The lambda values from the ecu are pretty much useless for evaluating a tune. Nobles/Rossions both use narrowband o2 sensors, which can only indicate richer than stoich (lambda 1.0, ~14.7 afr for...

What type of exhaust do you have? Stock or aftermarket?

What lambda values are you getting? Are you using a wide band, or trying to use the lambda readings from the Easimap software? The...

Are you running a stock tune or something else? Have you done a thorough check for vacuum leaks? A smoke machine is a great way to do this. How did you measure the manifold pressure at idle? The...

Why wait? It's pretty simple to change the mounts with the engine still in place...

We've actually run an engine on an engine Dyno, tuned it, measured the actual crank hp and torque, then dropped the engine in a Noble and run it on our chassis Dyno with the same tune. That's where...

What BSFC are you using, and which calculator? Our base number for drivetrain loss is more like 20% on our Dyno. Stock base fuel pressure on a Noble is 43.5 psi

We may have some of the connectors in stock...

You might want to take a look at an injector sizing calculator - 60 lbs seems a bit low for your horsepower target...

None of the US Nobles or Rossions that I have worked on have had journal-bearing turbos - they all have had ball-bearing turbos. Easy way to tell is to (with the engine off, of course) grab the...

Noble or Rossion?

Should be a link embedded in the post...
