CTR FN2 Throttle Pedal Remap?

[RobM77]

My wife's just bought a really nice 2007 CTR FN2 and she's over the moon with it. However, there's one problem inherent with the car that was present on all the ones we test drove and is still an annoyance 500 miles into ownership: the throttle responds too keenly at the top of the pedal travel. There's the customary very small delay before anything at all happens (as with most DBW systems) and then it's as if 20% movement opens the throttle by 50%. To me it feels like the effect the 'sport' button has in BMWs and Porsches. She's in the process of trying very hard to adapt to it, but we wondered if it's possible to remap the throttle to be linear - not messing with the engine mapping or anything like that, just the throttle.

thanks.

This might be possible, but you'll likely need an aftermarket ECU before you start doing any mapping, if the FN2 is the same as the EP3, and they do share the same engine, then you can't modify the standard ECU. You need a Hondata Kpro ECU, which iirc is about £500, then add your mapping cost. You probably can change the pedal mapping, I know you could do it on the first gen Astra VXR, which had a twitchy throttle in the initial travel but made little adjustment in the second half of the travel, so you could likely do it on the Honda, if the aftermarket ECU supports this function.

Thanks for the info.

Give TDi North a ring and ask them. If anyone knows it'll be them!

Agree with the above. The FD2 has the same problem, and I was given the same advice.

So...£500+ or re-calibrate yours/her right ankles!

(Believe me...it's not ideal but you get used to it...only time I have any trouble now is from cold, where it seems extra-sensitive...)

Have to say after 2 EP3 type R's I thought the DBW throttle on my FN2 was horrible. There was no resistance it hardly felt connected to the engine. Laggy too. I now have a 2008 S2000 which has DBW standard as it has VSA/TC but that is 100 time better and very close to the EP3 ones.

We're hoping that she gets used to it, yes. She's come from a proper car with cable throttle, no PAS, no servo brakes or in fact anything modern at all, so it's going to take a while to adjust I think.

I have to confess we don't find it too laggy; lag is our usual gripe with DBW cars and ruled out a huge number of potential candidates. The FN2's also got reasonable brake pedal weight - another annoyance with modern cars.

I think we'll give it a few months and see if she adjusts and if not, consider one of the options above. Thanks very much for all the info.
