Getting the AEM setup and realized it doesn't have the calibration data for BOE's Bosch IAT sensor ((should be p/n 0280130039). Aparently it is only used on VW, which is not in the AEM iat list.

Does anyone have the calibration table, or know where it can be found?

There are really only 2 possibilities. 99.9% of automotive IAT sensors and CLT sensors have 1 of two different profiles. With CLT sensors you can even validate your table by sticking it in some ice water and boiling water just to verify. If you look the sensor up on the bosch website you can probably also find their calibration table. I haven't tried this on an IAT sensor but they can probably also tolerate boiling water.

Easy solution, get the car really cold (first thing in the AM), make sure your CLT displays properly. Compare it to the IAT reading. If they're the same then you probably have it correct already, if not then pick another one from the list until the figures match. Recompare on a hot day after the vehicle has been at the same temp for a long time.

The table was definitely not on their website, though I found 3-5 values of the table which narrowed it down a little. I graphed all the IAT sensors listed in the AEM options, and a few of them were close so I am using them for now, but really need a full calibration table, and don't have an accurate thermometer to check it that way. I'll try checking it against the CLT sensor, but I would think BOE (or someone using the sensor for their setup) would already have the calibration table?

Anyone using the BOE IAT sensor mind looking at their table for a sec? :D

Here's the table I have, from maps being used by a few guys.

Position. Bits. Temp.
1. 0.000. 197.0
2. 64.00. 159.0
3. 96.00. 141.0
4. 128.0. 110.0
5. 160.0. 85.00
6. 192.0. 73.00
7. 240.0. 56.00
8. 288.0. 46.00
9. 336.0. 38.00
10. 384.0. 30.00
11. 432.0. 24.00
12. 480.0. 17.00
13. 528.0. 10.00
14. 576.0. 3.000
15. 624.0. -7.000
16. 672.0. -18.00
17. 720.0. -32.00
18. 768.0. -50.00
19. 816.0. -50.00
20. 864.0. -50.00

In my car, this table reads high at typical ambient temps. 5 degrees off at actual 12 degrees C.

Thanks!! :bow:
But is bits supposed to be Resistance? AEM table uses volts vs temp

Couldn't tell you. It's the table from an EFI Technology map, as used in the first gen BOE TVS setup. It is not linear, more of a double s curve, but pretty smooth.
