Have you checked your AC condenser and cleaned it out? Try doing that before you go buying $600 worth of radiator.

I see 180* cruise temps with an upgraded turbo, in texas heat.

Also, I didn't know you used different plugs for FI.

Thats part of what got me debating a better radiator, that and being in the desert. Thank you for the tip though.

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..

Idle Post 15
https://www.rx8club.com/series-i-eng...eed-ap-215661/

When adjusting, keep in mind
Temps in celcius
Speed in kmh


My idle is set to 875rpm
Fans are 186/188/194*f

Some threads that helped me learn...

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

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.
