Perfectly compatible with aftermarket exhaust , and if a dyno proven exhaust system like new smb is added, would further lead to greater hp gains.

No
Our ECU on the RX8 is very clever but cannot distinguish between types of exhausts so your tune can only really improve with a better catalyctic converter and free flowing exhaust .

Oh fair enough, I figured it was worth an ask if a different type of 98RON fuel was used can be detected.

I'm trying to think of performance mods to slap on that will maximise the potential of the tune.

Does anyone have recommendations, so far I've got a hymee + intermediate pipe thats about it. I've been in an rx8 with REVi and K&N and hated it.

Is the ECU available to us here in the USA? Maybe this has been asked already, if so forgive me. We've got 93 Octane where i am which is decent.

auzoom

g30ffman, There is no ecu change, purely a reflash of the ecu similar to what Mazda do at service. You have Racing Beat that already do this for you and Cobb Racing that are working on a hand reflasher. As for fuel, we use the RON octane rating whereas the USA uses something else (sorry to lazy to go look it up) but from memory your 91 is the same as our 95 and your 93 is the same as our 98.

RXP33D I would consider a lightened flywheel and reconsider the REVi.

Just the units are different... RON and something else (I can't be brother looking up either).

Just remember that US octane are fatter

takahashi

Our friend did not think REVi is as advertised in the review here either... . I think simple is the best in intakes... did you see my article? Check my blog.

that figure is on crank.... not wheel...

rexi888

The article clearly states that the 202.3 hp figure is at the wheels.
It would be a sad day if the best hp at the crank for a knightsport flashed 6 speed was 202.3 hp, let alone the 140hp for the stock automatic. Jeez, even my mums 1.6 ltr stock corolla puts out 100kw at the crank.
Even U.S rx8s are putting out about 185-190 hp consistently at the wheels in stock trim.

Yes...202hp is at crank..We have called up the dyno shop to enquire. But we also know that this particular dyno normally gives a lower figure then a dynapack.

erx8s

Do we have some figures on the increased Torque on this tune ?

Ben

g30ffman

Thanks everyone for the replies is the rb comparable to the knights ? If so id consider that

takahashi

The method should be the same - it is down to how good the tuner is working on your car

g30ffman

I was under the impression that i'd send the ecu to RB, they'd flash it and send it back? Or does someone have to tune it to fit the car once you get the ecu back? forgive me if the questions seem stupid and i admit i haven't searched using the search tool but i had originally subscribed to this thread and you guys are quite knowledgeable..

Thanks

takahashi

Our one will be individually tuned on the dyno. I suppose is the best tune. Sending your ECU over is just a "guess" work in my opinion.

auzoom

Yes, RB currently does a Mazda Style "flash" in the sense that all cars get the same. In this instance KS are tuning each ecu using on the dyno.

RXP33D

So replacement drop in filter is the best type do you think? Do you recommend using wet/dry type?

takahashi

I don't know about the best but I think there is minimal difference from what I have seen so far.

I will prefer pod style in a close cage, but then again it is much similar to drop in a good filer with some RAM intake mod.

I dunno dry or wet, but I don't think washable is what they advertised to be. I doubt the filter will be the same after each wash. So I will go dry type and change periodically.

Hey there everyone!!! Just a quick update....... (Not long to go now!!!)

I have the location of the Dyno establishment we will be using, Could all involved people please EMAIL me and i will foward on the details.

Also If anyone else is interested mail also to confirm numbers etc..

Regards Jas..

Jas

I have time today to change the spark plugs, all the oils and oil filter today. So it is a clean car for them to tune.

I will drop a clean filter later too. ....

Can't wait

BTW - the spark plug came out is not bad at all, but the car has extra tick when I put the foot down, rotary is very sensitive to good spark flow.

fdracer

Taka,

Definately a new set of plugs makes the world of difference to an engine designed to burn oil!!!! they get coated with deposits rather rapidly.
Ive seen alot of plug problems with rotaries over the last 11yrs of
playing with them!!

I`m still waiting for My ECU to come, so I can tune the 8, cant wait.....

Rest of the Knightsports shipment is due to arrive 2morrow also, i`ll get some pics up
when it comes to show you the dedication these guys have given us!!

Regards Jas...

auzoom

Taka left out that his plugs didnt "look" fouled, that was the strange part.

Jas when you say are you saying you are getting the tuning software yourself?

Would like to report that I have (finally) taken the RX for a good run this weekend. Loaded with 3-people, that little MSP engine was pulling hard.

I am confident that the engine is pulling noticeably better now.

Have also done an engine grounding kit of my own & have some 10mm IGN leads on their way too.

HKS-Twin power coming soon when there is spare cash.

Its using a Microtech LT10s with the stock ECU still in place, Getting the car dynoed this afternoon, will let you know how it goes.
I have road tuned it yesterday and i tell ya so far it feels great, wheelspin 1st second off the mark, very responsive power, say if you are hold ing it at 3000rpm thru a corner and gas it the power is right there.
WINTON HERE WE COME!!!!
