Thanks Adam I will definitely try it out.... Cheers!!

Good day Sirs, i have a Honda B16 NA engine. everytime i let off the gas pedal, AFR goes as rich as 9.5 before coming back to Idle AFR of 14.7 approximately. The duration it stays on rich AFR before returning to normal coincides with the duration delay i set for Fuel overrun fuel cut (Tq reduction / introduction time), which is currently set to 2seconds. While i understood having a rich AFR for a split second doesnt hurt, i am curious to see if theres any adjustability for this part. *I tuned it for 2 second delay for torque reduction because somehow it gave me better drivabilty when shifting gear and decelerating. Tried reducing to 1 second or zero delay, the car was jerky whenever throttle was let off. Any info would be very much appreciated Have a great day guys!! 16Jan23 updated fuel.pclr drivability check log.llg

HI Adam, i do have a working speed working on PC Link. Its set on DI 3 with LF wheel Speed. But somehow it doesnt show like how it does on the realdash.

Hi AdamW, i tried to set the data to show from DI3,4, 5 and 6. All was either showing '0' or '400' for speed. Am i missing anything ?

Hi... may i ask if the speed is supposed to be working on a Link G4+ ECU (Honda B16) connectes via USB OTG cable to my andriod device. I switched between ECU speed, GPS and TCU speed.all didnt seems to show any form of numbers...

Hi Adam, as per your suggestion. However, unfortunately i didnt notice much difference 24nov tune.pclr

Hi Adam, its actually currently running in open loop. As ive not fully sorted the issue, i was thinking i should leave it in open loop till i get it sorted then switch to closed loop.

Hi Adam, So i redid the throttle body adjustment and tuned the cold to warm idle. Still observe drop in RPM during AC clutch engagement. Any further advise? i guess something worth mentioning is that when the engine is still relatively cold (40-50deg ECT), the rpm doesnt drop so drastically till almost stalling. Is it because at that point of time, the idle target rpm is still at 1300, thus the AC load cant drag it down much?

Thanks Adam for tips, so i managed to tune up the car from cold start to warm idle. It idles well with the e-throttle target set at 2.0%, base position required was 0.3% to hit the Idle RPM Target. Everything is running fine and good in open loop, i also adjusted the idle up for engine fan, and it compensates for it very well with 0.5%. But these were only good UNTIL i turn on the A/C. with A/C on, the idle RPM tend to drop a fair bit before eventually catching up with target. I had to adjust the idle up for AC to 0.4% in order to achieve Idle RPM Target. but no matter what i do, the car always drop too low in its rpm when the AC clutch kicks in. I understand in the case of cable throttle body, the derivative gain MIGHT be able to help with the onset of load during A/C clutch engagement, is there anything i can do for e throttle? Also, during the drive, the car tends to stall whenever coming to a stop. This is my first time tuning with e throttle, any help would be very much appreciated. amos 22nov tune.pclr 22nov amos log.llg

So im helping my mate sort out his high idle on a honda B16B. His car idles at almost 2000RPM on cold start (typically about 30Deg Celcius here in Singapore). I saw that his E-throttle table top row were mostly Zeros, and seems like his idle was controlled by his 'Idle Base Position Table'. From what i read from the help file, i understand they are telling us to make the car idle by adjusting the top row of E-Throttle target table. And the Idle Base Position table should only be touched to help with cold start. Im planning to get his car to idle with warm engine with his 'Idle base position table' zero-ed out and purely by controlling the throttle opening with E-Throttle Target table. And subsequently do a tune from cold start to dial in his 'Idle Base Position table' Am i doing it right? is there anything i should be looking out for? Thanks in advance. amos 16 stock tune.pclr

Thank you very much Adam.. understood. Thanks for the very clear explaination!!

Hi, have some qjestion regarding VTEC tuning. 1. may i ask if the ignition timing is normally retarded or advanced when the engine cross into VTEC? I just got a Honda civic with a B16A (updgraded with B16B internals) in it.. downloaded the map and realised the ignition map seems to be 5-8deg more retarded in VTEC than in Low cam. Was thinking it should be advancing timing since the engine is higher in rpm.. would want to have the timing advanced to support combustion. 2. My Current map is set to switch between ignition tables 1 and 2 during VTEC engagement. Ive seen maps where there is only 1 table for ign. In this case, whether u r in vtec or not, we are using that table's timing correct? If this is correct, why would anyone want to do this? Pure simplicity of tune?

Okie.. understood...thanks you so much for the explaination.. cheers

Hi, i have a question regarding fuel tables, may i know why is the fuel table axis made to MGP, while the lambda target set to MAP? Shouldnt they be the same?
