  1. hi there thanks for the help. ended up being the ignition dwell control.has stoped the misfire and only drops 0.1 afr richer.wich I presume is allgood
  2. hi there I have changed the dead times to match the table above.also checked over the earths to the ecu. added 2 extra earths to the engine and battery.replaced the alternator and battery still much the same.it is ok till it warms up..only thing I have left to check are the power supplies to the ecu..I did have trouble with this ecu when I first got it.was sent for repair as it was trigging two injectors at once and was a solder joint that had bridged two injector drivers.just wondering if maybe something inside is causing this issue. thanks
  3. Thanks for all the help.just wondering if that would be the same for the stubby 875cc deka. I am currently trying to get the part number for the injectors from the supplier..it is running 40 psi fuel pressue and does not change with voltage.i will try these dead times and see if any improvement. also over the next few weeks I will check over the loom and check voltages at injectors and ground points.
  4. hi there I may have to check the loom for bad connections and maybe replace alternator.here is my map file and a log with engine up to operating temp idleing .Head lights are turned on atabout 20 seconds then turned off at 30.and back on at 40 seconds then engine fan turning on at around the 1 min mark..also the issue is not there while the engine is warming up. I did have the afr showing on the plot but after saving and reviewing it has disappeared. thanks help much appreciated. integra.pclr afr rich with head light or fan.llg
  5. Hi there I am new to using link and have an issue im trying to resolve,i have a da6 integra that was converted to obd1 from obd0 with a converter harness.all works has been working fine on several different ecu's for many years its is running a b18c turbo.i have recently purchased a set of 880cc siemens injectors and a link g4 + 95civic link plug in. All is working well apart from at idle and on light cruse when the engine fan turns on or head lights the engine stumbles like a miss fire and air fuel ratio on the wide band goes rich from 14.9 to about 13.8 .also sometimes coming to a stop the engine will stall if the rpm comes down too fast.. I have been supplied dead times from the supplier and according to them have never had to change these dead times for any vehicle they have fitted them into. I did notice that my voltage does drop about .9 of a volt.. thanks any advice would be much appreciated.
