  1. You need to make search ecu setting->write "fuel pump"-> select fuel pump control-> select speed control method and make it general xover and store and save it. It should change to fuel pump high speed mode.

    Strange misfire

    Everthing is perfect but I forgot to write here. And also I want to ask what is the highest exit decay rate I can use ? I used 20 but can I use higher like 40-50 is it safe ?

    Thank you for reply. I understand what you mean and deffinitely I will try and I hope issue will go. But I want ask that why it isn't enough to lock the timing to 16* from pclink and calibrate from distributor ? (Because I did that) I'm just asking to learn.

    B18C Link G4+

    Hello, I tried all but it did not work I have same issue again which is like a small misfire on every rpm randomly and when try to start engine sometimes it tries to start and stops sounds like engine timing is not ok but engine timing is ok by the way car runs fine with hondata ecu. So I want dig it more. Link ecu is obd1 plug in version and we are using it on a obd2a engine wire harness with conversion harness (which is good working condition) so is it possible to the problem is related with conversion harness or distributor (because distributor is obd2a also)? Link's base calibration is for b16a engine and this engine is b18c so does it related with that? Trigger or something should be different on calibration I use? Or can it be trigger offset which is set to "97" on Link base calibration, I sync the distributor but I did not change the value "97" I just locked the timing to 16 degrees and adjust the distributor with timing light.

    I will try first three. this is modelled tune and when I have the issue I changed to fuel equation to “traditional” (in cass I did something wrong) and I synced the timing which is off around 3 degrees but I have the same issue. So last trial time is synced and have the same issue again. If there is nothing wrong with the calibration (tooth settings, distirbutor settings etc) I think that isdue is on the distributor which is gone after some hours with hondata ecu. Thank you for quick reply.

    B18C Link G4+

    Hello, Today I tried to tune one of my fiends car which is sleeved b18c honda engine. Ecu is obd1 link plug in ecu. When I try to tune the ecu engine is strangely misfire or not misfire but bog for 1 second and continoue like afr is not ok but its ok off course. I did care and disconnet disributor socket before first calibration upload and I care for spark edge and select rising. Since engine is sleeve and have big bore pistons I wanted to use modelled fuel equeation and I entered correct engine cc and injector cc (injectors are stock for now so I wrote 240cc). First I tried with link base map injector dead times but later I tried with hondata's dead times for oem injectors because they are different. On link calibration 14v is 0.95ms and on hondata 14v is 0.49. I tried both dead times but same issue again. So I want to anyone check my calibration if I make a mistake (by the way calibration just tuned until 4000rpm because of engine break in). And also for trying we uninstall link ecu and put hondata s300 and engine runs very good but later (same day's night) distirbutor broken so may be the issue is warned distributor but I wanted to be sure. Since this plugin ecu is civic which civic's don't have b18c is there any difference for timing or injector phaseing? I already checked the calibration and I can not see and timing related setting except trigger mode "multi tooth" which they should be same for b16 and b18. VE Honda Civic 92-95 G4+ Xtreme Plugin.pclr

    Strange misfire

    Yes all logs engine misfires around 1 second right after gear change. Let me explain how its been. Push at 1st gear tyres starts to spin (drifting because of rwd) so hit the rev limiter and hold 1-2 seconds change to 2nd gear and misfire for 1 second after that misfire stops and tyre start to spin/drift again. This is same if you push at 3rd gear and change to 4th gear even if its not drifting.

    Strange misfire

    I change map sensor location (tried to cancel vibration), I measured voltage at idle for coils and they are ok 13.7 volts, I cleared statistics because of engine tuned from an other guy before so I want to have clear statistics. I have 3 log files and I attack calibration again with small changes.

    Strange misfire

    Hello everyone. Yesterday I tuned a Link atom ecu on Mercedes 190 chassis with sr20det engine. I didn't swap it one other mechanic swap it and tune it first. When I tune it there is no misfire and everything is smooth. The issue occurs after fast gear change. Let me explain more on tuning I told to owner put 3rd and make a pull from low revs till limiter and there is no misfire but when after I finish the tuning on the road let's say owner make a pull at 2nd gear (no misfire any rev range) and put it 3rd gear fast engine misfire for a second and gone I mean misfire stop and engine revs like a champ. I tried to lean it and gives more ignition advance (because ignition is safe side first place) and did not sort the problem. Owner says with other guys tuning its much worse so I tought I touch what is the problembut I can not find it. Ignition coils are audi r8 red coils, stock ignitior removed coils directly wired to ecu. I also tried to add more dwell time to coils. I tried at 14v 2.2-2.3ms at high revs. I'm also adding calibrations if someone can check it, I will be happy. SR20DET.pclr
  13. Thank you for reply and support.
  14. I'm the tuner, I tuned everywhere below 0.9 bar and all is good with part throttle and below 0.9bar. Thank you for reply. I will check rrob's adivse to see if its the issue. Might be injector settings but it should be correct at base map. I checked it now. "Speed Control Method" is off. may be this is the issue. What it should be? Can you help me please.
  15. Hello, Today I installed Link G4+ plug in ecu to evo 8. With stock evo 8 ecu air fuel ratio is 12-12.5 at 1.3 bar boost but on Link ecu at 0.9 bar after 5500 rpm air fuel ratio goes to lean 13.5-14. Of course I try to adjust it by increase injestor duty cycle but no result engine runs lean again. I also canceled the fuel pressure solenoid and result is same. So with stock ecu 1.3 bar afr is ok but on Link ecu 0.9 bar after 5500 rpm engine goes lean. What it can be the reason, what should I check ? Thank you.
