hi..

i have 2 systems integreated in my car.. an 91 civic with a swaped and boosted ZC in it.. all obd0

-in the ecu i have moates hulog
-on the side i have an Innovate LM2

both the loggers give off signals that are bouncing forth and back
this happens with the engine on and off (just with the ign. on)


first is the hulog, engine running and also a shot of the LM2 RPM bouncing like a mad man.. but if you look at the cluster it is nice and calm..

And then we have Logworks from innovate.. reading off the LM2 unit, tied into the OEM harnes (signal taken from the blue wire at the dizzy)

exactly the same happens when the car is off (just ign on engine not running)
i have redone the grounds, sanded down and made new ones with bigger gauge cables and what not...

the battery is rear mounted and i have redone that also.. i run ngk R plugs so that should not be the source (considering that this continues when the engine is not running)


so i have now turned to you.. please help me, kind of desperate here and the dragrace is closing in, 1 week from now and i need the dataloging to map it befor that..


thanks in adwance to anyone trying to help me!

 

you definetly have a wireing issue somewhere...who did you harness? the hulog should read rpms just fine of off the ecu if done properly. what ecu do you have?

 

done by myself.. it is a pm7 ecu

what could cause an interference like this then?

 

ok.. got the hondalog working using turboedit and ecu conntroll.. not BRE and its built in datalogg..


1 down, 1 to go..


any ideas on the LM2?
