Re: failsafe setting
 

It make no different to the system. It is only a signal.

From x1.5 to x2.5 it is only a 1.66x. You should be able to see up to 83%+ . You can check it with the FDC. It is good to have a signal comparable to the MAP sensor signal so that the pointer position IP/R trimmer is more central. Make it easier to see.

Need t0 un-solder x1.5 first before linking x2.5.

Let me know what you see with FDC linked.

Re: failsafe setting
 

Thanks. I will unsolder x1.5 then linking x2.5. How about the IDC gain? keep it 12 o'clock no change. Also the THRES ? now I setting at 11 o'clock ( one segment ), return to default 12 o'clock ??

Re: failsafe setting
 

The gain trimmer is for IDC + MPS after setting the PI-R trimmer.

Threshold is normally set to 36-42% (11-12 O/C). You can set it lower in summer.

Re: failsafe setting
 

Befor I unsolder x1.5 to linking x2.5 pre-amp gain. I check again FDC x 1.5. My gauge displayed upto 7 bars around 85%. So I still kept the pre-amp gain x1.5. Also I log my real fuel injectors duty cycle to compare with aquamist FDC. I found when real fuel duty cycle is 30 % the FDC is 36%. Real fuel duty cycle is 40% the gauge FDC is 50%. When real fuel duty cycle is 50 % the gauge FDC is 65% and real fuel duty cycle is 60% is gauge FDC is 85%. So may be I need to trimmer decrease IDC trimmer ? But I do not know which direction ( CW or CCW ) is decrease ? any advise thanks

Re: failsafe setting
 

I am glad you have checked it again. Your previous email mentioned around 50%. I would leave it at x1.5.

The x1.5 gain and the gauge is arbitrary. x1.0 is most the accurate. Pin16 (test pins) will show you a more accurate assessment of the IDC% compared to FDC.

Can you tell me which one of the three of the trimmers is referred as IDC trimmer. Thres, PI-R or Gain?

Re: failsafe setting
 

Please see the picture . 1. THRES : I set 11 o'clock ( 1 segement CCW). 2.P/I-R : default ( 50/50%) 3. Gain ( I hope to decrease ) 4.FS-DL : default 5. DIM : 9 o'clock more dark at headlight switch on. 6. Auxf-s: no use.

Where I can find pin16 ?

Re: failsafe setting
 

This looks quite normal. All other trimmers are at default except for the dim.

Pin 16 is on the first left of the bottom row of the 30 test points (above the jumper links). Use the GND pad as your 0V reference. It is marked "16"

Re: failsafe setting
 

Do you have a 0-5V WBO2 or EGT sensor signal?

Re: failsafe setting
 

I need to check my car EGT is 0-5v but my O2 sensor is narrow band not wide band. Still the same question.. how about my gain, if I will decrese it , I need to CCW ...

Re: failsafe setting
 

I found pin 16. But how to get the voltage during driving ?
