Re: Australian RIPP Install (RHD)

I'm confident they will. It feels like a diesel at idle but as soon as you hit 1K RPM it is fine. I've noticed no issues apart from this post my day or "hard" driving on the track.... still you want a no issues experience with such a mod.

Re: Australian RIPP Install (RHD)

Can only go with what I know from modifying my bikes, but after a big day spanking them, some times the power commander modules or in this case, the Diablo tuning module is learning or re-learning the car. I have had my Harley's get full custom Dyno tunes and then I hit it hard one day and the bike runs rough on low idle. I either hard reset the bike, or disconnect battery and back to normal. Only once did I have to take one of my bikes back to Dyno to get the rough idle tuned out. And the more you ride it, the better the bike becomes.

I think you are seeing your jeep learning the SC and how it operates. I'm expecting my jeep will be the same once it lands here and I get my RIPP installed. Rough idle is either to lean or can be too rich on fuel. Keep an eye on your gauges and use your 5 senses to gauge how the jeep is running. Sound and smell can tell a lot how a car is running. RIPP will be able to, or should be able to tell you where the issue lies, if it's a data issue.

This is only my 2 cents worth, and I have absolutely no experience in modding cars full stop. Only bikes.

Re: Australian RIPP Install (RHD)

RIPP got back suggesting to check the Spark Plugs and I took it the Jeep Service Centre (who did the install as well) and they agreed that it was probably just a spark plug (or maybe an injector). It is booked in for Monday and they said it was fine to drive (but keep off any hard driving till they check it out).

FYI - they also said they are seeing interest from other SRT customers so I let them know about the Group Buy (no idea if they will pass this on however).

RIPP also sent me this excerpt to keep in mind:
Quote:
****Road racing with the factory manifolds and cats is not advisable - the exhaust temps will get staggering and this light will trigger - Its heavily advised that if you go road racing a header be installed to disipate cylinder head temps and avoid high CAT temps. The rich code was trigger in an effort to save your engine, we fuel enrich and pull timing to cool cats down.

I cant remember if you have done any other mods nath ?
But with what ripps said you do need the correct supporting mods to have a reliable ride ie injectors, plugs, filters, exhaust full system . people say you dont need headers and so forth but hey more air in more out right?
more is more so you need the backup.
if you haven't got header skip at demon did mine cheaper shipped than i could get kooks here or in usa . TIP: dont try and install your self on RHD models

Re: Australian RIPP Install (RHD)

The pulled the spark plugs and a couple of them are shot while others look still new. He is thinking some crap may have gone through the system when the air filter came off as one is pitted (but thinks the rest of the engine componentry is fine and I've "dodged a bullet".... so looks like I'm just up for some replacement plugs). He has some pics that he is going to send. So while we wait for new plugs to arrive the existing ones have been re-gapped and while it is a bit better the idle is still rough (I'll be away for work most of the week anyway).

Pretty good service team at SVM Artarmon (Chatswood from next week), as they did not even charge me! Highly recommended.

Thanks
Nathan

I'm going with excessive heat!
We've been in contact with Nat via email as well.

Road racing with the stock manifolds/cats is not advisable - the heat from the cats can cause extensive heat at the cylinder head. The tune is designed to pull the timing back and richen up the fuel to cool the temps down. The plugs may have suffered during this process, we would bore scope it to check piston integrity and possibly do a compression test, just in case.

Hmm, something through the air filter? Check the superchargers impeller see if it has trace or marks of something ingested, even so how would it get past the intercooler? Unless is was sand.

That sounds like good advice.

Re: Australian RIPP Install (RHD)

So here is the close up pics and results.

"Cylinders 1 and 2 Spark Plugs Damaged....Carried out boroscope checks on all cylinders. Found slight marks on C1 and 2, rest of cylinders all OK."

We ended up replacing all spark plugs anyway and carried out the 1 year services and they think the "slight marks" are OK. Boro(e)scoped the SC impeller and that was fine. Compression test was also fine.

Post the service I'm getting some odd gear shifts in Auto (fine with the flappy paddle) and the occasional rough idle (and it seems to throw the Rich Fuel error still at this point) but both seem to be settling down and I've only driven it in traffic for about 1 hour. Spoke to the Service Centre who said the fuel monitor sensor may also be fouled from the rich exhaust and to see how it settles back in.

Thanks
Nathan

Re: Australian RIPP Install (RHD)

Ouch mate, this could get expensive?


I suppose those scratches will fill up with carbon quick enough?

Re: Australian RIPP Install (RHD)

Yeah lets see what RIPP say as I'm not sure if the scratches matter at all - Jeep did not seem to think so but....... qhy do I get the feeling I'm about to see a recommendation for forged pistons
