Hi, Thanks for taking time to have a look, I have corrected the idle speed vs coolant but have some questions about the air temp tables, (air temperature compensation tables in the fuel compensation tab)

I cant change the values on either the stock H22A calibration or on mine (bit if mine were the ...

Update,
I have recorded a datalog every time I drive the car, only once did it run lean (see datalog in previous post) I cant see anything wrong with the calibration or the datalog, except for the lambda.

Could it be one of the sensors causing an intermittent problem? or something wrong with the ...

I have attached my latest calibration, main changes are;

Closed loop, o2 sensor disabled, use wideband input for closed loop, voltage lambda conversion table corrected;
0.00 2.31 5.00
0.68 1.00 1.36

I have also attached a datalog that shows the running lean problem. it was fine when I uploaded it ...

I have attached 2 calibrations, car was running ok and did not show the lean issue, but it still may be of some use! are my target lambda tables correct? can you see any problems?

I willtry to get a log of when it is not running correctly.

I get a o2 sensor error code when its in closed loop I ...

EDIT - Now ok and wired in with ELD pin only going to white wideband input wire. (cut wire)

Thanks

So I should use pin D10 ELD? and not D14 O2?

or does it not matter as long as I select the correct input in smanager?

This shows pins are from left to right;
21,19,17,15
22,20,18,16


I am confused by this chart ;

Hi, sorry for the long delay in replying! Its not perfect but running better so have not looked in to it until now!

I have a AEM ueago but it is in open loop, so I now want to connect it up to the ecu, I have a P72 with a s300, am I correct in thinking that its as simple as connecting the white ...

Hi, My Prelude H22a has started running very lean but its not the calibration as its not all the time plus it was set up correctly when tuned. if I upload the same calibration again its fine for a while, seems to fix the problem and car runs correctly.

When its running correctly it idles file ...

Hi, sorry for the long delay, may be of some use to people still, let me know what you think of it, only problem with my car is that the emissions (CO) are a bit high!

I have a map from a similar setup that will do, you still need it?

Mat

Thanks for looking in to it, will do!

Hi, I have now uploaded to the ECU using an older version of Smanager and the engine runs normally, but since I updated the ECU firmware the Launch control still does not work on the air con switch (cant turn it off) I have checked the settings, inverted the input etc.

The calibration was from my ...

Hi, I have just downloaded the latest Smanager software and it prompted me up update my s300 p72's firmware before uploading my settings,

The engine does not seem to run the same as it was using the old firmware air fuel ratio is different at idle or driving etc. and the Launch controll cant be ...

Thanks for that, it makes sense now, it’s a shame there is not a spare output, so I don’t have to get rid of something!

Im not sure if it is a JDM or a USDM P72 it is the 3 plug one, would the JDM ECU have 4 plugs like my original P13?

Thanks, Mat

P72 ECU with s300, NOS control & Full throttle shift.

Hi, I want to Install my NOS kit, but need to learn more about how to integrate it with my ECU (JDM prelude H22a P72 ECU)

I don’t understand how the outputs work, can someone help explain the following, or point me in the direction of any old ...
