We were pleased to have been asked to develop a custom ECU calibration for Relic's turbo diesel project.

Softening the torque transition to enhance drivetrain life was not new to us, but were also able to yield a power delivery that is much akin to a VTEC engine.

I have spent some time in the car, and have to admit that it's very impressive! [smilie=thatworks.g:

When you have the intercooler kit sorted for my car, I would be well up for this.........:popcorn:

Do what you want a diesel is still a diesel...

Kiding! By the look of the dyno plots you guys have created something unique... great figures and great work getting the car to where it it.

Just goes to show what TDi are capable of...

Mark and DERV owners.

Relic let me have a drive in his car yesterday, words fail me to sum up how impressive it is.

I am SERIOUSLY impressed, Ive driven a stock one. Massive difference!

Thank you very much for your kind words Ash [smilie=thatworks.g:

Tuning modern diesels isn't as easy as some people think. A fairly high degree of attention needs to be paid to get the balance of torque production/smoke/mechanical sympathy right :)

Ash told me that even though his Type-R is heavily modified, Relic's derv would almost certainly cane his Type-R in a drag race...

It certainly felt that way. No disrespect to my FN2, but Relics car felt seriously quick.

Now I know he doesnt have as much bhp but torque figures certainly support that.

The scary thing is TDI have had to hold back torque!!

Thing is it delivers all the torque and doesnt make a song or dance about it.

Shame Wavetrak dont do an LSD for it.

:embarassed::dontknow:....

... dont know what you mean ash :p

Anyway, start hitting the corners and speeds over 70 I'll be left far behind.
Its just the way the torque curves, and gear ratios work.

You need to be awake alert and on the ball with the FN2 or put it in the hedge I'd imagine.
So I guess you have to be living it right in the moment when you are pushing on with all the brain cells firing at once.
With the diesel you do feel involved.. but there is still an air of detachment.
Whether thats a good thing or not..... dont know.

Do you rate the brakes ?
No idea how good anything is on the FN2 as I never drove one.
So I have no way to compare, especially with the extra weight of the derv.
Feel good to me....different dimension to stock anyway.

Roll on the next bonus...get the supension sorted.

I think theres more to be squeezed out this engine up top.
The hunt begins :lol:

Brakes were really good Relic, as good as mine. I think the second corners become involved you'd be left behind my FN2, cant comment for stock FN2. The only thing I wasnt blown away by was handling compared to the FN2, but then again I only took two corners!! lol

Does no one do an LSD for the DERV? I'd get a LSD and get weight down, change alloys? Do you have stock suspension + FRS?

More power? Maybe look at catback? I assume UK DERV Civics dont have a DPF yes?

Yours just felt it pulled really well. Of course I may be wrong about a drag race bit but when I had a go the torque everywhere was really impressive.

Next time I see you and my intake pipe is sorted your more than welcome to take mine for a spin (assuming you have insurance). I am quite often in Brentwood, in fact about 3 times a week so we could meet up?

Wavetrac will do one if there is a guinae pig and enough interest I think I was told once.
But yeah.... I wasnt expecting the handling to be upto yours. :D
Its totally stock at the moment ... still deciding on best way to attack it for the best results.

Koni str.t + eibach springs vs eibach coilovers.
The meister coilovers keep whispering at me too.... but adjustable top mounts arent required and can ware and get noisy evidently.
With coilovers I can adjust the weight distribution too.
That lot + FRS and polybushes should do as a start.
I am also still serioulsy interested in the old Skyline 17" wheels @ 6kg each.
http://www.civinfo.com/forum/wheels-tyres-suspension-brakes/48124-skyline-wheel-offer.html
..which should fit ....just and stick with the Type S style of 5 spoke wheel.
I like the OEM wheels....but losing the weight is more important.

In theory the unsprung weight to kerb weight ratio is 5:1 ~ 10:1
The audi guys reckon it was 8:1 down the drags strips accelration wise.
So say 11kg for the oem wheels = 4 * 5kg * 8 = 160kg equivalent kerb weight loss.
Which is like droppping me from 1453kg to 1293kg handling and accelleration wise.
Will also increase accelration rates by 12%.

I wouldnt want to drive your matey without proper insurance.
But I'd love to be a passenger... get a gauge on the kind of performance your car has in the twisties and in/out the bends.
Thanks very much :cool:

Exhaust is a sticky issue.
We can use any FN2 catback exhaust.
There is no DPF but we have 2 CATs.
The 2nd one is replaced by a dpf in europe... so can probably go.
Exhaust fabricators wont replace a CAT..103r approvel will see them fined if they do.
Which leaves me with a restrictive CAT stuck on the turbo.
70mm turbo back single exit like the Js 70rr would be perfect.
but getting 70mm off the turbo down is real, real tight if it was even possible.

Plus the airflow is pretty much at the limits of the turbo anyway.
So I've sent a couple of emails.
The flow limit might be exhaust...but I think its the turbo choke point.

Two cats, yikes. They must be adding a big restriction?

In my experience LSD and FRS gave the best handling improvements.

I mentioned alloys cause of unsprung weight, Im assuming your car is quite heavier than mine.

LSD feels great around track, FRS feels great in all driving conditions.

Interesting times ahead for you.

You say its only on track you really feel the LSD benefit.
Is that because you get better feel/control at the limits with the power, better traction out of the corners or simply you have more grip at the limits ?

Mine should be nearly 200kg heavier with the glass roof.... not 100% sure...this is worst case.
Might stick it on the weighbridge at the local dump.
