well i fronted up today to pik up my is200 & there was an issue with the car. they had just washed it so maybe that has something to do with it, but anyway car would start & run but it would cut out at idle. the car is an is200 with a rs200 (beams blacktop) conversion. it is/was running a power fc that has been tuned & when i drove it a few weeks ago it was fine. anyway the idle cutting out issue was temporarily solved by putting the stock ecu back in, the funny thing is on my way home (driving on the stock ecu VERY gently) it threw a check engine light. i dont know how to read the factory ecu error codes, but the place i got it from rekons the power fc is at fault, anyone got any ideas on what this could be? the tune was not changed, im wondering if a sensor was throwing a code to the pfc causing the motor to cut out & causing the cel? |

Is the stock ecu for the RS200 or the IS200. If its not the right one it could explain why its tossing codes. Also tend to agree with the Power FC being suspect, did water actually enter the unit when they washed the car ? Does the FC work after its had time to dry out. Not sure what your purchase rights are but is the seller prepared to do anything |

im not sure on the first question & unfortunately the bloke i bought it off is out of town for a couple of days (he left before i could collect the car, but left it at a respected jap import workshop in perth he has been cloesly associated with (used to run it) now something i didnt realise about the car is it looks to have been an auto originally (the aftermarket lsd makes sense in this respect - as well as the cruise control switch) so if it was the is200 ecu its probably an auto one - or it colud be now using the altezza manual ecu that would have come in the 1/2cut. i doubt water got on the powerfc it was installed correctly in the plastic box in the engine bay - its possible tho because i wasnt there when they washed it. I will go back to the workshop & see if they can test the fc again or at least read the error cel i am getting - first thing this moring it took about 7 minutes of very gentle driving before the cel came up again. i thought it might be engine temp related so i turned the car off & started it again but it still took 5 minutes or so for it to come back up again - i drove the remaining 20 kays to work with the light still on. The seller offered me the car at the price which included a working fc & tune so im sure he will stick to his word. the workshop manager agreed that the issue occured before i took delivery, but he wont do anything without the seller giving him the ok to have a look. The guy i bought it from is quite well known throughout oz in the jap import scene so im sure he will sort it out. thanks for the reply |

The cut out at idle could be a loose fuel pump relay, or crap connection on the cam angle sensor, located back passenger side of the block. I've had both those cause a similar problem while using a powerfc. |

you might be on to something there!!!!! when the fc was running the car they had datalogit plugged in & im sure they mentioned something about the fuel pump ecu which could be at fault (which didnt make sense to me) but if your saying fuel pump relay that gives me a good place to start looking. where is the fuel pump relay? in the smallish rectangular box in front of the battery? thanks |

Yeah it's in the box with all the relays... marked EFI or something can't remember, just bash all the relays in

i noticed last night that lid does not clip on too well.. hopefully my pfc is fine afterall! hopefully the CEL im getting now on the 'factory ecu' is related to this issue as well. thanks again. i might use this thread to ask about other 'new car issues' lol * the throttle seems to 'hang' when i take my foot off it for gear changes - its quite annoying - ive adjusted the slop out of the throttle cable although improved, its still there. (if the car is running the factory automatic ecu, could this have soemthing to do with it?) * tried the satnav at home & the map screen came up showing my correct current location - tried it today & it now thinks the car is ~20kms to the south - further investigation with the manual required i think. * i found the damper adjustment for the TT hsd coilovers (set of 4 only a few months old) on the front (top of strut), but the rears dont have adustment on the top of strut like the fronts?? so yet to find how to soften them up. * tacho (has altezza dash from 1/2cut) under reads something chronic - makes the car 'different' to drive since its got a 4.8:1 diff. dont know if this can be fixed? (will be using the power fc handcontroller to check revs if/when it gets reinstalled) thats about it for now! thanks |

The hang between gears might just be the super heavy factory flywheel keeping the revs up. Don't know if thats what you're talking about but could be something. and I'm pretty sure your tacho can be recalibrated by an auto sparky. |

the car has a non standard clutch (pedal is heavier than stock), but previous owner didnt know what flywheel was on there when i asked him if it was still the stock dual mass type. thanks for the info. |

why would this issue only cause problems with the fc? wouldnt the car cut out with the stock ecu too? i just spoke to the mech there & he recons the CEL im getting is due to the stock ecu not working with the conversion or something. cheers |

It probably would with the stock ecu too, but may not be as sensitive? Not sure, the stock ecu deals with stuff pretty well. But yes could be to do with the conversion on the stock ecu. |

agree with your first point there. funny thing is i can drive for 10 or 15minutes with the cel off (after a restart), i would have thought if the ecu didnt like something (maybe its the original auto ecu now with a manual drivetrain) it would realise straight away. anyway i removed/replaced the relay marked EFI & cel still pops up after a while. i have the powerfc here & i will try plugging it in & seeing what happens. cheers |

So is it a factory manual 3sge or auto 3sge. There are slight differences between the two and if your trying to run a manual 3sge with the auto 3sge ecu that could cause some problems, If the fuel pump relay was loose you'd get a sudden loss of power or intermittent shuddering from the motor, I don't think that it would give a Cel though, the OBD-I code PDF mentions nothing about the fuel pump. If you want to read the codes then bridge Tc & E1 on the diagnostics connector located by the Fan relay box, its the smaller one located near the passenger headlight. Count the number of flashes the Engine Light gives. More info on how to read the codes here. The fuel pump relay is labelled Circuit Opening Relay |

i believe the car was auto originally (rego papers show it as auto, has cruise control stalk (dont think it was avail on fact manuals?) the stock ecu in there now - i dont know if its from the rs200 manual halfcut or the factory auto? one - (i suspect its factory auto) but here is the latest news, i just plugged the fc back in and let it idle up to 86deg on the hand controler, turned on the aircon etc & its not stalling now at all. might leave the fc in there & keep the other ecu in the car just incase. thanks for the replies, really appreciate it |

If your car was originally a IS200 with the 1GFE Auto then there's no way the 1GFE Ecu will run the 3SGE motor. It probably wouldn't even plug into the loom, I'd hope it didn't anyway. Good luck with the PowerFC, maybe it did have a little moisture in it and has since dried out? I think in the PowerFC manual there's a initial startup learning sequence you need to do... Ok found it here, about 2 or 3 posts down. |

thanks for the clarication on that - it must be the altezza manual ecu then, so i dont know why that would throw a cel. Anyway, i just found something wrong with the handcontroller cord... the wire braid is exposed in 2 places (about 3mm long each) maybe it was earthing out?

It could be something to do with the wiring, but if your willing then plug in the standard ecu, drive it around until it Cel's then grab the codes off it, it may be something relating to the Throttle Control as you've mentioned it feels sluggish. Not good, tape it up and make sure nothings shorting out! |

thanks for the advice i noticed when the ignition is on & the bonnet up I can hear a high pitched noise which sounds like its coming from the throttle body. is that normal? cheers |

Generally it should make a hum and a slight whine as you move play with the throttle, if you could get those codes off the stock ecu then it would help alot. I have a spare throttle body with all the sensors if you need it. |

thanks for the offer but if the car needs anything i think the previous owner will be forthcoming. yes it makes a whining noise - sound like a abs pump. when i move the throttle the noise becomes 'scratchy' i might take a video but it sound like its normal - ive never seen a setup like that before. i havent bothered to get the fault codes off the ecu as the worshop can do that for me tomorrow hopefully - if not i will find the connector to short out & give it a try. thanks alot |

this is a photo i just took of the smaller of the 2 relay/fuse boxes in the engine bay. i cant find 'circuit opening relay' in either of the 2. only whats in the green boxes ive drawn in the pic & a EFI relay in the bigger of the 2fuse boxes according to this the car doesnt have a fuel pump relay?

Hmm, must be slightly different on the 1GFE, On the 3SGE there's a relay in the larger box by the battery labelled Circuit Opening Relay, this does the fuel pump. Its possible that during the conversion the relay was installed somewhere else, maybe talk to the guy that did the conversion. Yea it does sound a little scratchy, thats most likely the magnetic clutch inside the throttle motor doing its thing, you'll need to get it to CEL on the stock ecu before you can get the codes as removing the ECU resets its memory. Unfortunately the PowerFC doesn't have the same kind of diagnostics, it tends to just make do with what its got. |

thanks for the info, i will ask the guy when i see him next. ive left the stock ecu in for now & hopefully i will get the codes from it this afternoon. the throttle 'hang' is a bit of a pain in the arse - i can hold revs at say 2000, take my foot straight off & the revs go to 2200 before going down - very annoying. cheers |

Could be the TPS or APS on its way out? Codes will help diagnose anything out of whack. |

i had the car ead today. only one error code was present (it is a 3sge manual ecu btw) the code was 40 i think, but they said that refers to speed sensor - so seems related to the 1/2 cut conversion. pfc is plugged in & car is running fine on it now - no one knows what caused the issue, so im just going to keep the stock ecu in the car. with the other issues, the damper adjustment is on the top of the rear struts (just like the fronts) - the little knobs were very tight but they came good & the ride is great now. at first the w/shop tech thought there was no adjuster there either - we had to be aggresive in moving the boot lining & then i could see them. the satnav works great but on the way home from work it had my current position about 50kms north of where i actually was lol. whats the go with that, it cant lock onto a satelite or something? cheers |
