As the topic states, is the 0-5V output range of the AEM UEGO Gauge model still a problem with Hondata(S200 only accepts up to 3.84Volts) - even with the new S300 or is this problem history now?

 

The short answer is no. This is due to the problem being related to the analogue input which only guarantees a minimum 3.5V output from a 5V supply. One solution is to modify the ECU so that it uses a 12V supply for the input (IC22, pin 8). This should give you an output range of approximately 0-10V based on the following datasheet - http://www.njr.co.jp/pdf/ae/ae04046.pdf

Alternate Method 1 - http://www.marklamond.co.uk/pr...t.htm

Alternate Method 2 - Switch the chip to another device that can cover the full 0-5V range from a 5V power supply. This will most likely require an adaptor as the original package type isn't common anymore.

Alternate Method 3 - Add an extra input buffer that divides it down to work within the maximum range of the hardware. This will let you do other things like reduce the noise level more easily as well as leave the ECU untouched.

 

Thanks for the interest

More input, anyone?

 

Someone tell me this problem went away with a revised version of the AEM UEGO Gauge - true or false?

As far as I can understand from reading the datasheet that came with my AEM (purchased two weeks ago) it says that on P0/P1 (setting jumper) an AFR value of 16.75 the AEM gives about 3.3V. If this is true then and I'm not a complete dumbass - AEM has solved this issue or what?

 

bump for an answer

 

Thanks for the bump

 

 

What about the PLX ? Whats its voltage range?

 

bumo for the aem fix

the s300 software has an option for the plx wideband

what about the s200?
