Hi! We just got a 2008 E4 and has been previously modified and re-programmed. The current settings are just fine with one person in it but it over-heats too easily with passengers. We are looking for the factory parameters if anyone can help! Thank you. ---

Someone should have them. Changing computers may have lost my stored files. What overheats? What motor? ---

I have some stock notes. Let me scrounge them up. I’m guessing you have ability to read your present settings? Do you know who tweaked your controller? Define overheating- Controller or Motor? What motor is in this car? How long does it take before the warning? What terrain are you using this car in? What tires are you using? Is there thermal paste on the bottom of your controller? Do you have one of the finned heat sinks on the bottom of your controller? Does the heat sink have a fan? Is it working? I also have a theory I am working off the side that may cause a controller to overheat that is not related to settings. ---

The controller is not getting hot, only motor. Previous owner admitted the controller was re-programmed. We would like to get the OEM parameters. It is a 2008 with a t4 controller, 5hp motor. ---

The min field current is 70, max field current is 55, pedal down field rate is 5, field weakening current is 65, ratio of field to armature is 87. Which one should I adjust? Would prefer OEM numbers. Thank you. ---

8 max field current is 55, ← Is this a typo?? Should be up around 240~255 I’m not even sure how it would run with this low of a number. If NOT a typo, then it is good chance this is the cause. The last guy missed it. ---

No T4 on this spreadsheet, but T5 stock is. Seem to recall they are very similar. T5 was higher amperage for the elxd and e6 iirc. > [@Master spreadsheet with T1, T2, T3, & T4 settings](https://community.electricforum.com/t/master-spreadsheet-with-t1-t2-t3-t4-settings/16693): > > I’ve always envisioned how nice it would be if there was a big ole spreadsheet with tabs for each controller type showing the settings and what they do in layman’s speak. With everybody doing so many different things such as bigger or smaller wheels, standard and high voltage and other modifications I know this would be hard to make universal.

Range 0 to 30 amps Set 51 to 255 Resolution 0.147 amps per set unit Example Setting of 251=(251–51)x0.147 = 30 amps CAUTION: Do not set this function to a value less than 51. Important Note: The function is used to optimize motor and control performance and this setting will be determined by GE and OEM engineers at the time of vehicle development. This setting must not be changed by field personnel without the permission of the OEM. –end [https://shop.fsip.biz/Image/GetDocument/en/291](https://shop.fsip.biz/Image/GetDocument/en/291) Page 30. ---

Yes, 255 is a value. According to the doc range is 51 to 255. Multiplier is 0.147 amps per set unit so 255 x 0.0147 is 37.4. It sounds like 255 is even high so there is actually a conflict in the doc. Max value should be 251. JandM just wanted a stock setting. Nowhere in my field notes has found #8 set this low. It looks like his car is running around stuck around Min Field levels? ---
