This thread is to document and discuss DIY tuning with the mazdaEdit software from epifansoft and the Openport 2.0 from tactrix.
As you probably know this is the only option for DIY tuning in the UK, but there is next to no information about it on the forum and I only know of one other member that...
As the name suggests I'm interested in what aftermarket midpipe options are available with a type approved catalytic converter but with the most bore so as as to comply with UK and EU laws whilst maintaining a little performance.
I have obviously found 2.5" ta cat midpipes with and without...
I have a theory that the link pipe for the secondary air pipe has a negative effect on the tuning ( such as it is) of the exhaust
I did an experiment on my tubular manifold a few years ago where I blocked it off so each port was closed and found the airflow was increased at lowish rpm (...
in the continuing sage of trying to squeeze every last erg from a rexi I've come across this extra thin gearbox oil from redline, which is a new addition to their line
from here
basically its a 70W/ 75 compared to the normal MTL of 75W80 which we know works well
both are GL4 which...
Having a bit of a tinker at the weekend with Versatuner and some logging.
I'm making an assumption... Higher load = higher air flow meter reading = a good thing? I've overlaid auxiliary opening and VDI switching onto a log and tempted to say both should move a bit later... Versatuner has 2 values...
So, my class needs a cat. The standard cat is susceptible to blocking with carbon, but also as I understand it, the standard map is on the rich side to manage EGT's and look after the cat. I'm building an exhaust from scratch, so can put things where I want them. Any thoughts on the benefit of...
Need some advice guys; I've replaced my cat recently as it was blocked with a straight-through pipe but it was mated to the standard Mazda cat back exhaust. The exhaust is OK but the tips are getting past their best with corrosion & there's a good rattle coming from inside the back boxes, sounds...
Finally getting around to fitting my ram duct etc. John's asked the question of if there's anything we can do tuning wise that's simple enough for a minimap whilst we're also doing that.
I´m interested in acquiring a software to modify the Ecu of my RX8.
I have seen that there are 2 products: Versatune and Mazdaedit
Versatune works with the versalink usb interface and mazdaedit works with Openport.
I have seen that most of you use Mazdaedit, is it for some reason?
Which one do you...
It doesn't seem to have been covered much, and that's probably because the OEM intake system is pretty good, but in order to fit the engine into my Westfield the way I want to fit it, I need to lose around 60mm of height... and that means losing the standard setup. That leaves me with two options -...
Hi All, I have seen a post or two regarding the offset superpro kit, and also the whole oem vs poly saga. There was a hint towards one of you guys knowing the individual oem Bush part numbers rather than buying a whole arm, I have searched and failed to find any more on this, does anyone actually...
I'm intrigued that a silenced decat ( from TPS is £470, while a 'hi-flow' sports cat ( is £250.
My thoughts are that a silenced decat should be ideal for 364 days of the year, will reduce risk of damage and allow a richer fuel mix whilst not being too obnoxious for motorway hauls. But if a sports...
Looking at swapping the sump the next time I do an oil change and the main the one I can find is the greedy sump which seem's to have lots of good beinfits. Does anyone sell these other than pettit ? Or are there any other options on the market ?
Cheers
I realise the stock Rx8 inlet system is pretty good but having noted the IAT is pretty toasty in this heat I was wondering if it was worth drilling some holes in the plastic blanking grill behind the number plate to try and get some colder air into the nose. the air intake path does look a...
Hi Guys,
I found a new type of tuning box yesterday?
the highlights were you can hold up to ten remaps your self and choose which one you want to load into the car on a whim.
I see its usage would be if you wanted --
Standard tune
Street Performance
Street Performance with pops and bangs
Economy...
Let's kick off straight away with the issue of the subjective comment. Phrases like "it pulls stronger", "it revs faster", it's more urgent in the mid-range", and so on, are inadmissible as evidence!
Now let's deal with the question of whether porting really adds power, and whether it's worth it...
I intend to come back to this a little later, in its current form it is quite incomplete and will be by no means instructional - more an interesting little titbit.
Bearing clearances, oil flow and oil choice is more complicated than the generalisations in this post may make it seem.
Ok yes this is probably thought of a waste of time to some, but if done correctly the gains can be eye opening!
I've noticed the massive difference outputs std and even with the same ish tuned engines! This can mostly be due to tolerances of the spinny things being out and yes different oils,...
So hypothethical question for the boffins to mull over...
So we know each chamber has 2 coils and 2 sparks..a leading and a trailing and the trailing fires a short while after the leading in order to complete the burn due to the large combustion area..
The coils are fired by there individual...
Basically I have recently bought an r3 rx8 around 4 months ago on the basis that I was eventually going to get it rebuilt/full bridgeport and lightened after having it for a while or when the engine decided to go, but before I'd bought it the guy had a compression test on it and I'll attach...
so with the recent Dyno Might results that show PeteH's manifold to be the tweak of the week I thought I'd open the discussion
I've attached a spreadsheet with a rough calc for exhaust length and the key part of the calc is the exhaust cam timing BTDC so has anyone got any figure for an the...
I see that the PZ exhaust is often mentioned as being a good option for a nicer exhaust note? is it worth anything in cash and power over the stock exhaust? as I've been told that its a full Stainless system? is it any larger diameter? Is it louder than stock ( which would indicate its...
Hello to all....iv recently fitted the d585 coils and im looking to have a mini map done to change the dwell angles...i live near chippenham wilts and was wondering if any1 could give me info on the closest and best place to have this done...cheeers in advance.
Hi, this isn't my story so I won't mention any names (though hopefully the club members can add some more detail if they're so inclined) but I have had a report of an R3 being remapped to good effect:
"Hi mate, I've spoken to (club member). He's had a dyno session since the remap and the car is...
I'm in the process of rebuilding my lump and I have few ideas to improve power and would welcome your thoughts
1) bypass the water heating for the throttle body - this is added by OEM's to help with cold start emissions and fuel 'icing' in cold climates
not really required in the UK and a...
Being as the car is away at rotary revs having a tasty rebuild I find myself having a lot more free time which was spent on cleaning and collecting shell v power points.
As I'm aiming for high figures ( the 200 who mark) I started reading into why the rx8 does so s&*t on the dyno. I've been...
Ok guys, I've read posts until I'm half blind, and that has helped me in my quest to solve the issues that my second RX8 has....however, on the good one, where I have no issues, I'm wondering what a 192 needs to be uprated to 231......is it just a remap, or is the engine physically different ? If...
A few months ago I snapped a bolt on my aircon ( front of the engine bay next to the coolant tank ) a load of gas came out and it really didn't taste very nice !
I wasn't too bothered about the lack aircon as going into winter ect but looking forward I'm not sure what to do.
I'm looking at the...
Just wondering if anyone has had one? My mate is a quantum dealer and a reputable tuner, he's been on the scene for a while and knows what he's doing so was wondering if anyone has had one, failing that anyone know of a mazdaedit tuner round Oxfordshire/Berkshire. (My time off is limited, I work 7...
Hello everyone, please don't hate, I'm just sharing some knowledge from a different forum!
So back when I had my RenaultSport 200 (2liter one not the 1.6 panel shift model) I was also part of there owners club/forum, the guys over there were similar to here, either trying to squeeze as much power...
Hello. Just a quick one.
Managed to get a JDM car in today to have a look at the fuelling which was thought to be mapped richer on the bottom end resulting in apparently less grunt. This turned out to be not the case it seems.
Caveat: UK car was a 192 manual. JDM car was a 192 Auto. I have no other...
Just throwing this out here to gauge opinion as i am in the middle of planning and researching for a project that i want to get rolling within the next few months!!
I have heard bits about itb's being used for rx8s.
im not massively up on the mechanical side of the car/engine just yet.
So I'm mid RX8 race car NA build and feel with the mods being done a map of the standard ECU will help bring it all together.
My issue, the car is obviously not road going, I need to sort it all by 18th March and I live in the South West where no rotary mapping specialists appear to be based!
Firstly apologies if this has been covered before I couldnt find anything definative on the matter.
Ive almost bought a racing beat revi intake and duct a few times now when I get new parts withdraw symptoms and had to stop myself by convincing myself for £500 its not worth it.
So I'm sure this is something that's been asked a million times before but I can't find a clear answer on it......what sort of bhp can a 231 make without forced induction or porting?
Also I've read a few times that rx8s don't make the power Mazda claims they should have as standard, how much on...
I see Racing Beat do some lightened rotors although they are not cheap. I see there have been a few posts about this on the US forum. Makes the engine rev more freely and supposed to reduce wear. Anyone any thoughts on this?
