/\ I doubt that the CL tables do anything at over 100% load . Tests I did a while back showed CL only operates at very light loads .

I have it pretty close to perfect now . Did this by setting maf calibration at a point midway between WOT and part throttle . Then just adjusted the afr on the fueling table to gradually taper down from 100% load to 160% load .
This gives me the desired AFRs in all load situations but the fueling table (actual vs theoretical) is out by up to 10% in places

Hello Hymee and all you guys,

Please take a look at your emails because i need a VIN Token.

Thank you for your fast reply cause my RX8 SP needs a good PCM tuning with my manifold/midpipe/catback.

UP to just let you know i finally did it on my 192hp french Rx8 and it is just great.

We did 2 runs with GTECH and we saw that i had more power at higher revs and more torque at lower revs , so the engine is much smoother and responsive.

now i redline to 9000 instead of 7500 on my 192hp model and we managed to do a 0 to 100 km/h in 6.6 seconds which is quite good with 19 wheels and the PCM not quite recalibrated at that time, i am sure i can do a 6.3 run with 18 wheels after more kilometers which would be the time of a good 231 model.

also and most important it made my 02 sensor light disappear since i have a midpipe and we Scananalysed the car to check that everything was good.

so yes it's a great mod with a midpipe, it really changes the engine smoothness, thanks Mark of Hymee, Raspoutine in Rx8france and JMI my friend who made the fine tuning on my car.

Good work Tsar . Are you planning any FI mods or staying NA ?

Tsar

If FI means Turbo or Supercharger , guess i will stay NA cause here in france it is expensive for me to buy and it is hard to be delivered : a friend canceled 3 orders with Hymee, Pettit and Esmeril cause noone could deliver him quickly when he wanted / needed to.

Also here in france, few people can repair the rotary engines so definitly i will stay NA.

I have 3 "un-spoken for" S/C kits in production at the moment if you would like to let your friend know

Cheers,

Hymee,

Awaiting email answer from you.

How were you able to elimate the rear O2 CEL as as far as I am aware, Hymee has not added that functionality to the product as yet.

Tsar

indeed, it is only the fact of fine tuning the PCM engine that gets the CEL away and I find it natural since for me it is the goal of Pro Tuner : exploiting the fact of not having a catalystor anymore and so adapt the PCM to this change and make everything work normaly, and it leads to no more cell and perfect engine performance.

on the other hand if you just wish to erase a cell without "repairing" your problems just by clicking a button in a software, i find this method not good cause your engine will never work perfectly and you might even damage your mechanic on the mid term.

(sorry for my english, remember i'm french)

If you want good performance you tune for good performance .You cannot tune for no cels . It does not work that way . The fact that you don't get a cel is your good luck . I was lucky also when i ran a midpipe when NA and did not get a cel .
I think it could be to do with earlier 03 -04 models having slightly different parameters for throwing a cel .

Yeah, you can't "tune" out the CEL.
The PCM looks for a difference before and after the CAT. If there is no difference (regardless of actual lambda), it will throw the code.
It also takes a series of drive cycles.
The '03/'04 PCM has a different "tolerance" than the '05 - up PCM.

Tsar

Ok guys, i didn't see things this way : for me the CEL was there because my engine was too rich and i thought that the CEL went off because of fine tuning it.

I will tell your advise to our french forum because everyone thinks that goal of PCM tuning is good performance and no more CEL .

Symbioticgenius

Hey Hymee. You ever get that Pro tuner to work with 09's?
I remember you saying you only needed some numbers or something? if that's the case I might be able to provide you with them soon.

fastlaneracing

As said it dosent work that way, you can have the best tune in the world and still get a CEL for a missing catalyst. O2 front and O2 Back just look for a known difference between them.

Hymee

I just need a CalID - a good scan tool will report it - to start with. I need to stop by me dealer and check out an '09.

Cheers,
Hymee.

Hi guys, a little video to show you how is it on a french 192 SP manual model with exedy flywheel and midpipe, 9000 rpm now and more torque everywhere :

/\ heh - you might have to disable your beeper as is seems to be on more often than not ..

Brettus

iTrader: (2)

Hey hymee - i see you are on this thread atm

Can you tell me how to increase the load scaling above 200% please ? I'm right on 200 at peak torque and want to go another 10% or so .. Cheers

Tsar

if it is simple, i would be happy to do it indeed.

i guess it's a mechanical process between the dashboard linked to the tachymeter ? (please reply by MP if you a topic knowledge on this forum to show me or an answer thks)

Hymee

Reflash the Dash I'm sure it can be done...

rotarenvy

any tuning recommendations for the VE table above 125% load?

Brettus

iTrader: (2)

Here is mine - not perfect but does the job for me

Major changes on this table - will alter your AF ratio so be careful ...

rotarenvy

thanks brettus

how are the ve numbers applied? say you have a 1.05 will that add fuel for a lower lambda?

Brettus

iTrader: (2)

Edited ...

The only reason I can see to even bother using the Ve table is to help even up your fueling table so that target = actual .

Kane

iTrader: (1)

Yep that it is....once your MAF and injectors are scaled; this is the map I use to get my target and actual the same....

Though I have always gone backwards, more VE% = more fuel... so a 1.05 would add fuel and a .95 would take it out.

Seems to work for me.
