Yes, because the S2000 setting isn't specific, its still "universal". I used the coolant calibration from AEM and recalibrated it and all is well now. If you don't correct the Infinity table it will read higher.

I have been running the infinity with flex fuel for close to a year now and have virtually all the kinks ironed out. Only two things left that I notice is that the dash coolant readout will zero to 1 bar at 190f then comes back to 3 bars above or below it. Not sure if its a setting or a glitch. Other is when letting off throttle or coasting, RPMs will dip but im pretty sure that aspect is all in the tune.

Other than that it behaves like OEM in most situations such as idle and so on.

I also have KPRO4. I am having it looked into, but the butt dyno just feels like that car is more responsive and has more pep on the Infinity. The Infinity is also running a GM open element air sensor and gives a much better IAT reading where the Kpro still uses that shitty plastic element on the manifold and is horrible prone to heat soak. My theory is that maybe the tune was assuming IATS were a lot higher and is taking away timing across the map.

I'm gonna re-cal with the above parameters and see if it will fix my coolant temps.

The settings worked great for me! Any point to getting the Ohms right on the negative numbers?

Hey guys, I realize this thread is a bit outdated but wanted to see how everyone was doing with getting the correct table/calibration for the coolant temp sensor?
I recently upgraded to Infinity and my temps just cruising around are reading 210-218 which is ridiculous ( it's definitely not that hot ).
I'll be hooking up the computer tonight to compare tables to the ones posted previously.
My infinity was purchased in November by the previous buyer but we updated to the latest firmware prior to tuning it a couple of weeks ago.
Thanks for any input/tips etc.

Check this out.
Got the infinity installed and tuned in February. Car ran awesome (best ever). I also installed the gageART which connects to the infinity via AEMnet and gives your digital gages. The gaugeArt would work for about 3 minutes then freeze. It never made an entire trip. In April i had a trackday - consistent backfire and spudder beyond 7k rpm. I pitted the car and scratched my head. i changed the plugs, then the coil packs, then the map sensor, tightened the terminals on the map sensor, then the valve adjust. the mf still sometimes backfired and spuddered …it never ran consistantly well. then it became more consistent at 5k. this problem lasted through August. September - I called the tuner. hooked up the lap top and drove on I-10. We couldnt figure it out but he was telling me these ridiculous temps he was seeing! The temp in NOLA that day was about 94 and our highest reading on the Infinity was 239!! My ap1 has never seen over 3 bars and i just knew it wasnt really overheating. we got back to the shop, we looked at the Protect tab on the Wizard and there it was -> a table showing that fuel is cut above 5k rpm IF the infinity sees >215*!!! It made perfect sense as to why the car ran good in the morning and poor in the evening. We increased the temps 15* just to test if it would correct it. It ran like solid gold. and Lagniappe, as we say in NOLA, the gaugeART stopped freezing due to the editing of the table in the Protect tab. My guess is that the gaugeART would freeze when the engine would spudder (due to the fuel cut). I left the shop knowing my car can run like it did in February (colder temps) and thinking that i had a faulty coolant temp sensor. Tonight i got on the computer to order a temp sensor, but fortunately for me, i found this thread and am now way more aware of my situation. i dont need a temp sensor or fan switch. I will now correct the calibration and actually have an accurate temp reading! THANKS

Is there still not a concrete software update/fix for this issue? Do we just have to tune around it? Getting my 02 s2000 tuned with the Infinity soon. Thanks in advance for any info.

No software update/fix is necessary as sensor calibrations are entirely user definable. The known good coolant temp sensor characterization has been posted in this thread already but AEM has since also added a S2000 specific coolant temperature sensor characterization in the setup wizard. All you need to to is select it from the "Basic Sensors" > "Coolant Temp Sensor Setup" section and you'll be good to go.

Thank you!

I forgot to post a follow up on mine...
I went back through my sensor settings and the tuner had selected something like 00-05 Honda instead of 00-05 s2000... whichever it was, it was directly above or below the s2000 spec in Infinity. When I switched to the s2000 calibration I double checked all of the specs and they are perfectly inline with what others have posted above:

C F Ohms
0 32 6205
10 50 3920
20 68 2454
30 86 1604
40 104 1072
50 122 738
60 140 535
70 158 387
80 176 284
90 194 210
100 212 159
110 230 121
120 248 95
130 266 75
140 284 60

When I switched to this my intake and coolant temps at start up were almost identical ( when before they were off by 25-30 degrees) and everything stays much more in line with where I expect the temps should be... usually 180-190 depending on driving conditions. My temp gun on the temp sensor verifies the current calibration is much closer.
