I should have one up in the roof original one, removed when crunched the air box and pod filter was put on since there was a 12 week wait for new airbox from France.... Never got put back on (or the brand new airbox) because I liked the induction noise too much.Woah. That's pretty fascinating. I started reading this: https://www.brighthubengineering.co...ake-resonators-improve-volumetric-efficiency/
Looks like I'm in the hunt for one of those now, as the size/volume and neck shape is tuned to the engine.
Awesome - Yeah, I've rigged something makeshift up, but the original would be correct volume etc.I should have one up in the roof original one, removed when crunched the air box and pod filter was put on since there was a 12 week wait for new airbox from France....

No good to me now (had kept them in case I ever wanted to put the S16 back to stock) since my S16 has gone to heaven..

I'll see if anything else turns up in the short term, but if nothing does, I'll grab one.I’ve got a couple of 5’s.
You might need the Peugeot Sport chip, although that's probably not your idle issue. Let me if you want one, I've just made a few. Best talk to Cam85 who has just been through all this, with the same specs.Note that this is S16 306 (XU10J4), everything has been cleaned well and is very refreshed. It's a decked head, stage 1 inlet cam, 1.9L injectors, forged pistons, so there is a bit of difference to the tune.
Where’s the vss on the s16s? Is the the plug that connects to the gearbox housing with the plastic gear that gives you your Speedo reading. When I took it out the other night to bed the brakes my Speedo was working... is this the same thing?Mine did this also but eventually cleared after going over everything as you have done. I never worked out what it was but I would also check the VSS is working and plugged in.
Mine used to sometimes almost stall even once I was ‘happy’ with it. I believe the chip from Peter made a great deal of difference. I think it has to do with the ignition timing more that mixtures when its falling from revs to idle. Try turning the ignition on and off 20 or so times without turning on the car. This apparently can reset the ICV
Once you fit the chip you wont believe the difference in performance.
They really need a ‘tune’ which can be done on these ecus. The chip will help a lot. Theres a real hard pull from 5500-7500
Yeah will get that chip ad the first port of call as soon as it comes and see what happens - that way I don’t have to mess about with fuel everywhere. Then I can go back to standard injectors if it’s still ‘nervous’ catching its breath on idle.I'd put the old injectors back in temporarily just to confirm if it's mixture related. You'll have the chip today/tomorrow, which will help confirm it one way or the other. I know with Cam's it took a bit of mucking around but we eventually got it right. Did you contact him?
As in, take it to a tuner and put it on a dyno? You can program these ecus?Mine did this also but eventually cleared after going over everything as you have done. I never worked out what it was but I would also check the VSS is working and plugged in.

I don’t have a vac gauge, but happy to buy one. Will pick one up now. Chip just arrived.That behaviour is more typical of an engine losing vacuum, as it returns to idle. The increase in CR and later inlet valve closing, would have cancelled each other out, in that respect. Having an idle richer than 14.7:1 now is not going to hurt it. If anything, it should be happier. I'd be double checking for any chances of a vacuum leak. Do you have a vacuum gauge handy?
