I actually did have a noise coming from the factory idle pullies - I ended up replacing both with pulleys from Raceseng - I still have the additional pulley that came from the kit and it's not making noise for me (yet...)

So yes you can just install it and run it, but you will have a CEL.

regarding the pulleys, honestly I have a squeak and I have replaced that idler pulley. I'm fairly certain its coming from the alternator but it comes and goes so I haven't bothered really examining it lol

Thanks. But curious...if we connect the sensor analog output wire to the blue wire that runs to the ECU, would it still throw a CEL code? I'd like to be able to datalog my AFR via ecutek.

Do you know what's the size/spec for the alternator pulley?

Looks like raceseng no longer sells just the idler pulleys on its own. It only comes with the full pulley kit.

Could you also do me a favour and take measurements (ID, OD, Width) of the factory idler pulleys that you removed? I'll try and find a replacement part from Nuline as well.

That sucks - I got the set from FT86SpeedFactory in October but I know they waited a little while for them straight from raceseng - if they aren't selling them anymore by themselves that sucks because they are really well made pieces.

You need to disable the rear O2 sensor CEL codes, remove the rear O2 sensor adjustment range and then configure a custom map to give you an AFR from the WBO2 voltage. Essentially it'll need a remap.

So I just replaced the idler pulley with Nuline EP075, but still getting the squeaking noises.

Also removed one of the two factory metal idler pulleys (the top one directly under charger pulley) to inspect but as far as I could tell it seemed fine and spun smoothly. No play on the bearings too. I'd assume the lower idler pulley would be fine as well.

Don't really know what else to check. Anyways the noise disappears entirely after about 10mins driving once the engine is fully warmed up.

Replacing that pulley did absolutely nothing for my squeaking. Mine used to squeak for 30secs, then it'd go away. Now, it's a few mins...then the squeaking is gone. Someone else in this thread, said it was the alternator pulley that appears to be the culprit.

But I don't see how the alternator pulley could be the culprit....it doesn't have any bearings (that could fail) it's simply bolted to the alternator shaft and spins with the shaft.

The more current the alternator pushes, the greater the load on it.

The more the battery has been discharged, the more the alternator resists spinning.

If you want to monitor your AFRs using a wideband, you could also just weld in another sensor bung and mount the wideband in it.That's what I've done.

Sorry but I still don't understand how the alternator pulley itself could be causing the squeaks....that's what I was trying to say.

If truly the alternator, it drags and the belt squeaks over it until the battery charges up enough.

I don't quite understand how it could be the culprit either. However, some have claimed that they have removed the belt and spun the alternator pulley and it was squeaking for them.

I'm a bit frustrated with the squeak (just really annoyed by it). I'd LOVE to get to the bottom of it and fix it once and for all. It's obviously a very common issue, as many of us with the Innovate kit seem to have it.

Any idea why it would only happen the first minute, then go away?
