Good luck mate....i hate fault finding
I had a so called ECU expert fit, tune my E11v2 Haltech ..
The idle speed control was connected to #5 cylinder injector which gave me grief when engine was cold due to over fueling..Didn't do my ISC any good either..
So OFF to Haltech tuner [Hitman]
Injectors, ignition was re wired with DIS ignition [4 coils,wasted spark] $1200 and 4 days work wella 483 rwkw, engine started and idled as it should!!.. To think I drove around for 18 months like that! Even the odd club dyno comp, day at wakefield Pk..Then had with 372 RWKW..
Injectors #5 was burnt out [don't know why!!Lol] was injected 100 % time.. SO $1k for a new set of 85Lb injectors!!!
I didn't save one cent by going to a so called expert.. Stay away from
The Sparky.. Infact
RUN... FAST !!!
If it has a rising rate fuel reg ? This can cause running issues as its outside ECU, leaving tune unstable..
If its NOT tuned on load [road or dyno] it is nearly imposable to tune especially without wide band 02 sensor...
If it wasn't an aftermarket block, forged assembly it may have been a big grenade..
Umm?? Running this rich is no good for ring bedding in either..
