Thanks Adam. In the end it was spark plugs. I traced injectors the lot, after two days of fault finding... its the simple things. Car is now in for mapping (again). Noted on the ethrottle, I have been having poor idling I imagine this will help. out of curiosuty @Adamw, the https://www.haltech.com/product/ht-010920-bosch-145-psi-fluid-pressure-and-temperature-sensor/ is that the same as the 10 bar bosch 0 261 230 340 in the cal files? the car is being mapped for maxiumum economy and the standard b18c engine plug is a NGK IRIDIUM BKR7EIX-11 plug 1.1mm gap i believe by the end figure, would you recommend a change of plug for lean burning at all? or aggresive spark?

Honda Civic 96-99 G4X Xtreme Plugin - 025 new injectors - fpr fuel pressure sensor installed.pclx Please see attached - I changed the master fuel ms and it helped somewhat, but once again at full temp its idling with issues again PC Datalog - 2023-02-12 3;16;42 pm.llgx

Apologies forgot the map file - I will re check and sort another log as I think I have changed it since then

@Adamw Can I use the ISC solenoid on another aux other than 1/2/3/4? Also I am unable to update to the latest firmware as I still have the safe mode error from the last update. I also seem to have an odd issue with fuelling and what seems to be injector issues - even though I have moved them around to ensure these new bosch ev14s are not at fault - log attached I have updated to the new link software just incase, and its rather on and off, if I turn idle control / ignition control off it some times stabilises. I thought I was struggling with low duty cycle at 2% but then it ran perfectly fine once turning everything of @1.3% for a while. I am lost. I will place oem injectors back in tomorrow to double check and report back. PC Datalog - 2023-02-11 6;03;14 pm.llgx

@aerace_fab Honda Civic 96-99 G4X Xtreme Plugin - 022 knockplay.zip As per DM - @aerace_fab do I adjust each cylinder until they are even? using the ind cyl knock gain @Adamw @aerace_fabI have posted my map above - I have the car mapped on a dyno and she is running very well, but as my main goal is MPG, I was wondering what method if any I could deply to increase my mpg. I am aware of the ability of learn burn on low load, and to advance timing, could you provide some advice? also I have observed other people suggesting vtec triggering a 4d/5d table. is this a more proficient way of doing things. I fear I am in a position where if I were to change my mgp vtec trigger this would alter things and leave me with a flawed map. I often find myself not needing vtec on motorway speeds in the uk the way it triggers over is quite nice / only when you need it. but I do wonder if I am loosing mpg by not being mapped correctly off vtec due to my current configuration.

Thanks again @Adamw- I will refine and balance the cylinders against medium load/revs

do I need to worry that I got the same noise reading with and without the sensor connected? Do you have a link ( i think I have seen you post it before on how to setup logging ) for when I need to send you my map and logs in the future for support - and I imagine that includes my map file also. i noticed you post this link before on setup of knock - do link have a setup guide on knock control - tuning. Or do i need to go to people like hp academy to learn? Thanks you.

@Adamw 1. I seem to have noise on the line, even when I have no sensor, or loom attached, is this normal? the furthest right blip/rev was with the sensor connected - no change. Am i missing something? 2. pin out - is this correct? knock to D6 Sensor ground and shield ground to D13 below is the link pin out to support worked a treat thank you

Here are the OBD1 and OBD2a pin outs https://docs.google.com/spreadsheets/d/1nzmWjTXbOE_ahcjIUDzNgva-g7iIL0AE/edit?usp=sharing&ouid=110945455569194839967&rtpof=true&sd=true

Hey Adam, what was the reason you advised “Change Idle actuator integral gain to 0.03.” ? For my own learning / knowledge. Many thanks

Hey All, I know it is nothing special, but I imagine plenty of people were wanting to do this to a civic of their choice and perhaps could of done with a guide - or outline of what it takes, so I will do a write up. (I am not a professional to be clear) Project is still ongoing and looking to eek more and more mpg out of the old girl. And I imagine there are better ways of doing a better job! My name is Christopher and I am from the UK I have recently purchased a Ferrari Mondial and plan on dropping a K24 in it, hopefully putting a link in that car too! I will drop in the thread my pin outs and my adaptions on the harness converter to help anyone who needs support. Car info - 1993 Honda Del Sol / OBD1 Car was an OBD1 B16a2 and used a an OBD1 to OBD2a adapter loom (a reverse loom I believe is what they call it https://www.speedfactoryracing.net/products/speedfactory-obd1-to-obd2a-reverse-ecu-conversion-harness?_pos=2&_sid=51c622e73&_ss=r) I chose a B18C6 Engine which is OBD2a. Using an S80 LSD box with 4.7 FD, with a Integra LS 0.714 5th gear to eek out more mpg / lower revs at motorway speeds (has a handy shorter ratio 1/2/3rd gear too) Items used so far - Purchased an OBD2a HC96X unit - as this had knock sensor input vs the 92x (still need to setup) - I would argue after buying the below ethrottle and wideband module, perhaps the standalone units monsoon/open loomed etc would of been a better choice - but the plug in capability was a great appeal to me. Link Ethrottle Module Link Wideband Module 2x Link Expansion cables OBD1 female to OBD2a male adapter loop 3D printed throttle body adapter (carbin fibre mixed extruded) I chose a Bosch ethrottle / 68mm - I chose this as it calculated out at closer to the OEM throttle body volume, as the smaller, yet similar in diameter to OEM throttle body was lower in area due to the size of the butterfly's centre support. The honda throttle body had a machined down spindle for greater flow. I imagine the bosch unit is a lot sturdier due to its use in turbo aplication - https://www.bosch-motorsport.com/content/downloads/Raceparts/Resources/pdf/Data Sheet_68749835_Electronic_Throttle_Body.pdf For APS or PPS depending from where you are from - The ePedal I chose a rather generic and widely available unit from an Audi TT / Audi TT 8N 6 Speed Automatic Accelerator Pedal 8N2723503B. This unit had a kick down feature in the form of a sprung bump stop, so nothing flashy there. I also used a OBD2a distributor from the Integra DC2 to ensure the correct ignition system (Honda Acura OEM Ignition Distributor Assy 30100-P73-A02(TD-87U) B16 B18 CIVIC) with a OBD1 to OBD2a 10pin Converter. This was genuine and meant for the B18C6 engine. Be aware you will need to match (I believe) the trigger arming thresholds if you use the earlier OBD1 distributor, as when I was experimented it was the difference between firing up and not! I also converted the cars carbon canister activation / aka purge valve to a PWM Purge valve from the later b18 Integra. Not required but I wished to do so to ensure maximum fuel vapour recorvery from the tank. Base Map usage - "Honda Civic 96-99 G4X Xtreme Plugin not tuned" Pinout Diagram Google Sheet of Pinout - this is my active export - so I will be changing things as I go on based on my requirements. Active Discussion Open question and discussion thread I have on going - Purchase and Questions I will follow up with more detail as time goes on!

Thank you - Just seen this and will have a go - Appreciated as ever @Adamw

Any chance a 2 button cruise control could be created (up and down button) hold up for on/enable hold down to resume tap up for speed increase and down for lower

Perfect thank you @adamw I have noticed your previous post on IACV delete on a b series ("https://forums.linkecu.com/topic/12123-iacv-delete/") - idle ignition control when removing the Idle control valve - you used the following settings (below) Would this translate to below min max system as shown (below)? I am using it as we speak as a test, and its idling lovely now, am i missing anything which may put the car at risk?
