How easy is it to remap
Discussion
Going to stick the noble on a rolling road next week to see how many horses have left the stable. I hear loads of noble drivers have remapped their cars but the two centres I have spoken too say they can't. Just wanted to know what the score is and how expensive this could be. If you can give me the heads up would really appreciate it

Hi thanks for the advice and yes just got the old ecu so will get it checked first then see the man! what kind of extra Bhp can he get out of the old ecu ?
Our cars suffer restrictions which prevent turning up the wick to a significant degree.The ECU is not the governing factor, it's overcoming the various restrictions.
For a completely standard car, I guess you may get another (say) 20bhp before running into some other restricting factor.
For example, to get my 3R to 400bhp (standard MBE ECU), I did the following:
Aftermarket exhaust - improve exhaust flow
Bigger intercooler - improve air flow
Replacement fuel pump -improve fuel flow
Stiffer valve springs - prevents 'bounce' at higher rpm
Replacement turbo actuators
The slippery slope in search of more power then begins

P.S. mine was measured at 320bhp before the remap, so I'd lost 30bhp somewhere down the road. The increase of 80bhp made a significant difference.
All I'd say is before you even book yourself in for any mapping work get your fuel pump wiring replaced for some heavier gauge and relay it from the battery or starter.
When you get your figures at the end there will always be a reason why it couldn't achieve more and the hardest part is accepting that 'it is what it is.' Mine would have made more if my exhaust wasn't so restrictive, so I changed the exhaust. Next time it will be something else and no doubt I'll change that too.
Very slippery slope, be warned!!

Well stuck on the rolling road and got a bit of a shock. Had expected it not to be perfect and it definitely wasn't. It came out at 255 bhp so only 95 down. It's being looked at on Monday. Fuel and air mix to start off I will be happy to only loose 30 bhp at this rate. Kinda know why people take there cars to jet stream.
One thing to remember is that numbers off a chassis dyno are not absolute - they vary from machine to machine, and can be influenced by many factors. Some factors are within the control of the dyno operator, and some aren't. For example, car setup is important, but most dyno operators will assume that the customer has set the car up properly beforehand. Such things as tire pressure, wheel alignment, throttle adjustment, fuel pressure, etc. can all change the numbers you get off a dyno significantly, but most dyno operators will just assume that they're all set properly. Some of the factors that are under the control of the dyno operator include how they tie down your car, the gear that they use for the runs, how they have their machines setup, how they maintain their machines, accuracy and location of environmental sensors, etc. All of these variables make it almost impossible to compare numbers from one dyno to another, including comparing results to numbers thrown around by other shops, manufacturers, or off the internet.
About the only time that you can really trust comparison numbers is if you go to a dyno shop that has a lot of experience with your particular make/model car, and has enough data to tell you the averages for the cars that they've actually run on their equipment. For instance, on our dyno, we have over a thousand runs from Nobles in various states of tune. If I ran another Noble, I can give you a pretty good idea of how it matches up with the other cars. But, on the flip side, we probably only have a handful of Honda runs - I would have no idea if a Honda that we run is good or bad in comparison to others.
Anyway, just keep this in mind - depending on the dyno, and how you got your 350 hp target, you may not be as far off as it seems...

Well got the car back a couple of days ago I'll be straight it's showing 276 bhp and the torque is up about 80 lbs. The car feels compleatly different. The car feels very lively and will spin in 2nd and 3rd I'm not going to get bothered about bhp. The car feels right and the best it's felt in the 4.5 years I've had it

But it's still down on power so somethings not right? I'd get it to Jetstream or Noble motorsport for a check-over. That must be the lowest powered Noble around. Gassing Station | Noble | Top of Page | What's New | My Stuff
