I have a couple of cars here that I have tuned with Hondata Flashpro with different modifications so you can get an idea of what to expect.

1. This car came to me with an HKS intake installed. I had already tested these on my car and saw an 8bhp gain over standard but I don't have any before runs with this to show. This plot shows the HKS intake on its own, then again after I have tuned it with the Flashpro.

View attachment HKS & Flashpro.pdf

2. This car came to me standard and I installed a GruppeM, RRC intake and Milltek catback. It retains the standard manifold and cat hence the dip in torque after 5000rpm

View attachment Stock vs intake,RRC&catback.pdf

3, This car is the HUK test car. Was measured standard and again with Mugen intake, Mugen manifold with cat and Mugen exhaust. Again the dip is due to the restriction of the cat.

4. This is a car with a GruppeM, Mugen throttle body, RRC intake manifold, Toda manifold and Milltek catback. No dip at 5000 due to being de-catted.
(This car was making a good 5bhp more earlier on the dyno but this is the final plot after fully tuning all the cam angles and was running very hot.)

5. The car has the following modifications:
JDM/FD2 camshafts, GruppeM intake, Mugen throttle body, RRC manifold and Hondata IMG, TDi/XO supplied manifold, HKS catback.

6. CT Supercharger (Stage 3)
The dotted plot is with Toda manifold and stock intake and exhaust.
The solid line is with the HKS Race intake and custom single exit catback.

View attachment Terry CT Stage 3.pdf

7. CPL intake and Flashpro. Dip at 3500 was a massive rich spot like you get with the AEM,s but I tuned it out when calibrated MAF sensor on the road after dyno tuning. Not actually there now if tested again.

8. Mugen intake with scoop, Mugen TB, RRC intake manifold, Toda catback but tested with TDi/XO manifold and Toda.
Solid line is the Toda. Note that although the Toda makes far better figures across the midrange the TDi/XO one having the longer primaries is more suited to high rpm power making better peak bhp. This was originally designed by a company that made race manifolds where very high rpm was needed. I think with upped limiters to say 9000 you would see the gaps getting bigger making more over the Toda. CPL manifold was also tested and was very similar to the Toda in torque shape and made less torque than the Toda but more than the TDi/XO and it made less peak bhp than both the others.

9. Had a chance to play with a totally stock car before we fitted a few mods so this is the results of a bone stock car before and after dyno tuning with the Flashpro.

View attachment FN2 Stock vs Dyno tuned.pdf

10. I have here a car that has a GruppeM intake, Mugen Throttle body, RRC intake, Toda manifold and Milltek catback. The tune is done with these mods and can be seen as the dotted line on the graph below. We did this run then fitted a Toda catback and re-tested it. I tuned the car to the new exhaust system and it shows significant gains right upto 7000rpm where the slightly larger diameter of the Milltek shows through and makes fractionally more peak power.

11. This car has basic HKS intake and a Magnex exhaust and is Flashpro tuned. We fitted the oil Balancer shaft delete kit to it and just ran it on the dyno. No extra tuning was done.

12. This is a comparison with the Rotrex Sport kit and the Sport+ or Supersport. The only difference is the Sport is supplied without the intercooler/race radiator setup. I must point out that this is different cars but with very similar modifications. Both have HKS intake kits, one has an HKS catback, the other a Magnex. Both cars retain their stock exhaust manifolds and cats.

View attachment Rotrex comparison with and without intercooler.pdf

12. This graph shows the Rotrex comparison shown in the previous graph along with a car tuned with a Toda Race manifold. (Long dashed line) It is the Sport+ kit with intercooler, HKS intake and Toda catback. (Comments box is missing but as I can't overlay more than 2 sets of comments but it made 358.1bhp/8497rpm and 221.9ft/lb)

View attachment Rotrex comparison ALL.pdf

13. This graph has been requested quite a lot and although different cars and different mods shows the clear difference between a fast road camshaft and a "Drag" spec camshaft where you want one for midrange drivability and the other to hold a flat torque curve so you can increase the rev limiter and still make power.

Just a clarification..
..are you saying the CAT is restrictive or just adversely effecting the pulse tuning ?

Cat really affects the midrange but you can get higher torque developed through the increased back pressure when you set the cam angles to suit.
Also does reduce peak gains.

Do you mean spreading the inlet/exhaust lobes ?

Yes. On the Type-R we have upto 50' inlet cam advance as well as Vtec.
when tuning I lock the cams then tune each cam angle then overlay the lot and see what cam angles make best power at what rpm. That gives me the composite cam angle map. Its repeated low and high cam, low with vtec at say 7000 and high at say 3000 then the 2 are overlaid which then gives optimum vtec point where high starts making more power than the low cam.

Thanks...very interesting and clever stuff :cool:

This car is pretty new with only 3000 miles on the clock. I would expect it to loosen up with more miles and make a bit more power but its not bad for pretty simple bolt-ons.:cool:


The car has the following modifications:
JDM/FD2 camshafts, GruppeM intake, Mugen throttle body, RRC manifold and Hondata IMG, TDi/XO supplied manifold, HKS catback.

View attachment JDM cams.pdf

The car made 241bhp at the end of tuning so was very hot and peak had dropped several bhp over the time of tuning. Torque is/was a good 10ft/lb over stock cams. Certainly something to consider as its not a massive big job and still retains stock valvesprings so no need to drop the engine.

what are the gains about this spec list? arround HP
- RRC manifold (orginale intake)
- toda maniold
- invidia catback
- tuned with flashpro

I had standard 205hp and with the invidia i had 213HP

Regards,

230 as an estimate. Possibly better if you swap your intake as stock is restrictive unless your using a scoop

One question: The 1st setup with the HKS intake kit, is it tuned with a MAP or MAF based Flashpro map?

Thanks

All are MAF tuned. You don't need to tune MAP unless you have supercharger, turbo or wild cams that throw pulses of air back up the intake that disturb the MAF sensor readings.

Mate...thats a beautiful curve you done on Terrys CT.
Well done.....must be smooth as silk through the gears.
