Following on from a previous thread, can anyone confirm if there's much to be gained from remapping a "standard" FQ 360 without adding other upgraded parts?

cheers

Anyone know the BHP at FW?? Extremist, do you know of contact number for the garage who upgrated the 360?

You already have a fuel pump and a pretty nice exhaust, even if the 3" brigade insist it is dimensionally challenged. I like the FQ360 maps - the VVT, ignition timing are nice and the fuelling is good for torque and a touch rich at the top, probably not losing much power but making it safe especially with a cat.

What I don't like is the boost control - it runs no fuel cut and open loop boost. A boost controller on the standard map or simply a remap of the boost control would virtually optimise it IMHO.

The stock airbox lid is a little restrictive, it is simple to improve like this even if some think it is aesthetically dodgy:

Go to the next two pics. This still controls induction temps but almost halves the inlet restriction to almost the level of a good induction kit.

I reckon that if you bypassed the second boost solenoid and used a fixed restrictor the boost could be dramatically improved.

John,
What have you done [mods] to your car?, as i can see you have also changed the exhaust.I was going to change the front pipe of my 320, to an HKS unit, before the ECUTEK.What do you think?.I dont think you would get a lot of benefit from dumping the standard Super Drager, and fitting a more free fowing item, but maybe the front pipe is a good idea.Also, does changing the elbow produce massive gains?Do you get much induction noise with the airbox lid like it is. Regards, SIMON. :)

I got the car with Ecutek, Walbro, 3" Mongoose (original elbow), HKS EVC V.

I've remapped it with ECUflash, changed the airbox lid and fitted an AVC-R. It now performs far better. The induction noise is a little louder, but the HKS panel filter (from the dealer) makes more difference than the airbox lid mod to noise.

I started to get fed up with the noise, so for now I have the HKS catback on the car. Whilst there is a bore mismatch from 3-2.5-2.75" across the flange at the back of the cat the volume is more tolerable. It doesn't feel slower and holds the same boost, takes the same timing etc. However, I'm waiting for a 3" cat to retry with the original 3" Mongoose catback section. Another option is to flare up the HKS catback section to have a 3" flange.

I gather from other's testing that there is a very small difference between 2.5" and 3" for downpipe and cat at about the 400 BHP level. I would like to achieve good emissions/noise with 3" at least to the catback if possible though.

The 360 despite its expense is so good except the boost control and that would be very easy to improve either by ECU changes, boost controller or just playing intelligently with restrictors with a bit of datalogging to setup.

I don't think many of the pro-tuners will have seen just how good the mapping is on the 360 other than boost because they can't read the 360 map only overwrite it. I think some tuners will be overwriting it with inferior maps (except for boost).

Can anyone advise best option, Ecutec etc??
Put a HKS power flow (reloaded) open air filter and perhaps a boost gauge to monitor boost levels before diving into ECUTEK.

You may well surprise yourself :crackup:

:D

I've been running the 360 maps for a bit now. There are indeed very nice, but as John says, the boost control needs some adjustments for saftey. Very nice mid range response and earlier spool then the 320 or 340 from the MIVEC remap. More boost can be added for extra fun though :)

If you are at all technical and have the inclination you could consider doing it yourself.

John how bad was the noise on the Mongoose? I've got a IX GSR and I'm about to start doing some mods but the exhaust is a tough choice as its a daily driver and I don't want it loud!

It isn't terrible, it is just that I don't like loud cars. The resonators in it are shorter/smaller than the stock FQ system. It is noticeably louder than that, but not completely different if you see what I mean.

FQ system with bung in sounded ideal for most driving, although when thrashing the car you could mainly hear the roar of the engine from the front, and I think that non-Scooby 4 pots sound characterless, not a nice noise and it is restrictive. So I want an exhaust that is just loud enough to hear over the actual direct engine noise IYSWIM.

It doesn't sound that bad then, sounds like you want it a little bit quieter than me. I had a mongoose on my old escort cossie and I liked that, it would get on your nerves on a long motorway journey though...

Thanks for the info.

John,
I seem to be on your wave length at the mo.I just picked my new 9 up today, and did the 130 mile journey home with the "BUNG" in place.This is the first time i have driven an Evo with bung in place, and i thought it was more than acceptable, and i felt i could drive to Scotland, with no noise irritations.I wonder how many other owners replace the bungs if they are doing long motorway journeys.On another note, dont you just forget how good the Evos are when you havent been involved for a while.The feel of the car on the road, the razor sharp steering/direction changes, the torque from a slight movement of your bunions, its just great to be back in one again.Hey, im a happy guy :D :cool: :rockon: Regards, SIMON.
