Newbie Advice needed - First performance car in United Kingdom
OK so after reading the New Member threads and other posts in here I know I am make a lot of people feel like this
BUt...after being told this is the best source of assistance here goes...
I have just put a deposit down on this RX8 KURO which I will buy with 6 months tax included on Saturday dependent upon the outcome of an independant AA Car Check I have organised to make sure its not going to fall apart!!
Used Mazda Rx8 Coupe Kuro 4dr in Bristol, Avon | Car Kings
I have NEVER owned a performance car before and will be using this rarely, i.e. Sunday driving out in the countryside... I wanted a sports car for the summer for some excitement.
Now, i know very very little about cars in general, let alone rotary engines and high performance motors. BUT I have bought myself some literature, and downloaded a TON of notes on the RX8 in order to try and educate myself so I can take good care of this car...
I am hoping that some kind souls will assist me in my quest by providing a list (i dont care if its 5, 10, 20 things) that I can/MUST do in order to keep my RX8 in best condidtion possible given the above detail...
I already guessed that every Saturday morning I need to be checking the oil; I need to make sure I dont drive it cold on very short journeys; If i see anything weird (by weird Im not even sure what that may be :S ) with the temps etc to get them checked immediately.
Any and ALL tips, advice, must do's I will immediately compile a list and stick it to my dash until it becomes second nature!!!
I thank you one and all deeply

See the last post in the New Owner's thread, linked in my signature.
Make sure a rotary compression test is on that list, done at a Mazda dealer. Know the health of the engine BEFORE you buy.

you can run Denso plugs...some of the FI guys swear by them because they are cooler...the plugs not the guys
if you're FI you need to address your cooling immediately and even then youre still sitting on a timebomb unless you have a custom engine build made to handle FI
(water pump, t-stat, tune your fans with the Cobb)

Well I'm having cooling issues and I THINK it may be my thermostat due to my radiator seems fine, no leaks, hoses perfect and all that jazz. So i figured why not since i have FI and the like. The AC condenser is still lookin new as well. Everything looks new and seems new, but isn't acting new.
Thats part of what got me debating a better radiator, that and being in the desert. Thank you for the tip though.

You guys are awesome for the help. I plan on spraying out the condenser, but we've pretty much boiled it down to the rad, it's the stock with a REmedy thermostat in it. I'm gonna get a mishi performance rad. And gonna take that opportunity to do the coolant how i want.
Well you wouldn't be completely off key. I'm from AL and my neck literally stays red all year long. ha.
skimming through this post I read "redneck"

As I learn more and more, I've become increasing aware that I need to be keeping an eye on the oil temperature and pressure as well as my current OBDII system for watching the water temperature. Do the series 2 cars have any options for monitoring oil temperature and pressure? I know the Racing Beat gauges & pods won't fit in the series 2 cars, and I don't trust myself to do an A-pillar style gauge pod due to the air bags - will a shop even do this kind of install or is it illegal for them to disable the A-pillar air bag? Any recommendations?

Hay guys... I got a question on fan Trigger Temps..
I have an access port and I know you can adjust the fan trigger points with the AP.. Im just wondering how to do this with the tuner race program, and what are good points for idle, low speed driving etc.. Just a simple how to if that is available. I looked for something and I cannot find anything on it..
Oh yea Bonus question: Is there a way to control the Drive by wire throttle imput with the access port as well? If so how is this done with the AP? Or does an addition throttle controller fix this issue? Any thoughts on this would help as well..
Thanks..

any threads laying around that describe how exactly an ECC works? Happened to see a diagram of the pulley system recently, wondered how it correlated with coil/plug timing.
#2039
Are you asking how to adjust it in atr, or how to load the map on your car?

Those are the diagnostics tests internal to the ECU, they aren't "codes" in the traditional sense. Google "Foxed CA RX-8", open the RX-8 factory manual from the link, and look at the ECU troubleshooting section. Has all the detail.

Thanks for all your help man..
quick question.
In the fan adjustment folder of the TR program.
I adjusted these points.
Fan 1-A
Radiator Fan Threshold: Fan 1-A
85 Coolant Temp. (originally 97)
Fan 1-B
86 coolant Temp (originally 97)
Fan 2-ECT
90 Coolent Temp (originally 101)
Are there any needed adjustments for:
Fan 1-A Hysteresis: 3 coolant temp.
Fan 1-B Hysteresis: 3 coolant temp.
Fan2-ECT Hysteresis: 3 coolant temp.
or the
Fan 2-VSS=10 Vehicle Speed
Fan 2-VSS Hysteresis: 2 Vehicle Speed
Thanks again.

I set my fan VSS to 30kph (about 19mph) because I've got a big ol' intercooler obstructing the primary path to my radiator.
Unless you've got something blocking it you're probably good with the default.

ok..im back had Jujitsu class and had to change the oil on my girlfriends honda fit.. haha.. But Yea I'm N/A so I didn't think i needed to be adjusted but i wasn't sure..
#2047
SO I was looking at this and I wanted to get an idea of the LTFT menu in the TR but I can find it..
I did a few data logs using MM info and I was wanted to know how to scale the MAF with what I got but I seem to be missing some information. OR looking in the wrong spot on the TR program. any help?

Simple method:
Take some logs, the technique described in MMs thread is fine. You just need data from idle, cruising, 2nd gear full throttle, and 3rd or 4th full throttle.
Cleaning the MAF is a good idea.
Scaling the MAF table at the low end is the easiest way to eliminate fuel trims. Reducing fuel trims is important, because the long-term fuel trim (LTFT) that is developed under highway cruising conditions in closed-loop will affect full-throttle open-loop fuel delivery.
LTFTs are set over three ranges.
1-9 grams/second
9-20 g/sec
20-200 g/sec
Just select each range, hit m, and multiply the values by the error you are seeing in the log for that range.
For the last range, there is no need to scale the MAF beyond 100g/sec.
Iterate until the trims approach zero.
Adjust the fuel tables for gears 1-2 and 3-4 based on your full-throttle logs.
Iterate until you see the AFR you want. Best power is usually in the mid-13s, it is may be safer to aim for high 12s.
I find a visual log viewer like MegaLogViewer is a much easier way to view logs.
For the OMP, just increase the values in the load-based table.
I can't find it right now, but I have a Mazda research paper in which they measured oil delivery rate vs wall temperature. Temp decreases with increasing oil delivery, and then flat-lines.
In other words, there is an optimal point, but the only problem in going beyond the optimum is increased oil consumption. I have an OMP adapter/tank, and I like the smell of premixy exhaust, so have this table adjusted liberally.

Adjust the coil dwell times.
Done.
Not the way I do it, but I think this method is easy enough, and will probably give 95% of the improvements possible on an NA car.

Adjust the coil dwell times.
Done.
Not the way I do it, but I think this method is easy enough, and will probably give 95% of the improvements possible on an NA car.

Plastic shield protecting something??
Hello. Let me just put out there that I do not know much about cars at all. I own a 2004 RX8. My boyfriend looked under the front of my car and there is this piece of plastic that looks like it is a shield to protect something. Mine is pretty ripped up.
Does anyone know what the name of this part is called? Should I take it into the shop? How important is this plastic shield?
Thank you in advance,
Melissa

Not sure what you're exactly asking here?
It's also hard to tell how much of this post is Oltmann's or yours.
Can you clean it up a little?
First thing is there is no "LTFT" menu in TR and by TR I'm guessing you mean the Access Turner Race software.
Taking data logs using one of MM's maps isn't going to get you anywhere if your intent is to make changes. You can't change Jeff's maps.
Or are you saying you used the style Jeff's asks for when submitting data logs?
If you want to try and tune (scale your Maf) you need to start from an open Stock Style Map.
Try either the Stage 1 or Stock Style map that is provided with the Cobb AP.
If you want help scaling the Maf you're going to have to be very specific about what you're asking and provide the data log file as well.
This isn't likely the best thread for a discussion like this but meh why the heck not. lol

SO I was looking at this and I wanted to get an idea of the LTFT menu in the TR but I can find it..
I did a few data logs using MM info and I was wanted to know how to scale the MAF with what I got but I seem to be missing some information. OR looking in the wrong spot on the TR program. any help?

Simple method:
Take some logs, the technique described in MMs thread is fine. You just need data from idle, cruising, 2nd gear full throttle, and 3rd or 4th full throttle.
Cleaning the MAF is a good idea.
Scaling the MAF table at the low end is the easiest way to eliminate fuel trims. Reducing fuel trims is important, because the long-term fuel trim (LTFT) that is developed under highway cruising conditions in closed-loop will affect full-throttle open-loop fuel delivery.
LTFTs are set over three ranges.
1-9 grams/second
9-20 g/sec
20-200 g/sec
Just select each range, hit m, and multiply the values by the error you are seeing in the log for that range.
For the last range, there is no need to scale the MAF beyond 100g/sec.
Iterate until the trims approach zero.
Adjust the fuel tables for gears 1-2 and 3-4 based on your full-throttle logs.
Iterate until you see the AFR you want. Best power is usually in the mid-13s, it is may be safer to aim for high 12s.
I find a visual log viewer like MegaLogViewer is a much easier way to view logs.
For the OMP, just increase the values in the load-based table.
I can't find it right now, but I have a Mazda research paper in which they measured oil delivery rate vs wall temperature. Temp decreases with increasing oil delivery, and then flat-lines.
In other words, there is an optimal point, but the only problem in going beyond the optimum is increased oil consumption. I have an OMP adapter/tank, and I like the smell of premixy exhaust, so have this table adjusted liberally.
