two part question -



1. for anyone - anyone installed a D1R sc on a tip? thoughts?

2. for Flash and/or Pete - any available?



havent been here in a while and am just taking a lazy way out. but it proves that i still live.



have decided to keep the two 968s and fix everything wrong with both. not a lot but a few niggling things. the cayman s will not stay. the cab will get the sc.

we've only done 1. i wasn't exactly prepared to get into the tip tuning at the time, but the kit got sold to a tip anyway. he installed it and then trailered the car out to me for tuning. after some pretty serious massaging of the tuning, it ran well, but i failed to check the 6 minute timer. as it turned out the car has a knock sensor issue that we have yet to see if we fixed. the problem is that the head has been shaved, which makes the compression a bit higher. i'm pretty sure the tuning is perfect for a normal thickness head, but i think i may have to make a couple of tweaks on his car. the owner just hasn't had the time to deal with it. i'm ready when he is though.



to answer the question though, it will be ready when the next batch comes up, and will be sold exclusively through the D1R site. watch for the announcement on that one.



it will still require the correct ECU though. i have not yet been able to resolve the issue with the early one.

Hi. I'm the Tip SC owner. As Flash said, I'm trying to isolate a knock sensor problem that came on at the same time as the SC install. I took the knock sensor off a couple weeks ago and cleaned the contacts and retorqued. I cleared the codes and it has not come back in the form of a blink code. The code I was getting was 1-2-3-1. It's an intermittent knock sensor 1 code, but I think I need the durametric to see how frequently it's happening. I've just put myself (and the durametric) a the bottom of my own Christmas list, if you catch my drift.



The symtom I have is that after 6 minutes, the revs get cut back from about 6200 to about 5500 RPM. The car feels as though you hit the rev limiter - fuel cuts out. Prior to the 6 minutes it will rev and shift normally with the throttle all the way to the floor.



In preparation for the SC kit, I had my head redone. It has some pitting from the degraded head gasket and they took about 10 thousands off the head. As a result, my compression went up, perhaps contributing to the problem.



As for the performance, it's intoxicating. The shifting is smooth and puts gobs more torque in the corners. The kit installs exactly as it does on the manual, with the exception of a cooling line that must be removed (maybe adds 10 minutes to the install).

This probably has noting to do with your problem but I'll share just in case. This happened several years prior to the SC kits. I was running a performance chip in a 944 and in talking with the developer of that chip mentioned that I owned a 968. He had been working on a chip for the 968 and asked me if I would like to run a test version. It took him a couple of tries but finally it turned out to be quite a good chip. In the interim the car would shift at <acronym title='wide open throttle'>WOT</acronym> around 5500. As best I remember he had not seen the problem with the 6 speed car testing. For some reason the computer was going into a sort of safe mode due to a problem with the code. It has been too long for me to remember what he said the problem was but once fixed the car revved like it should before shifting. I have also seen this situation in the Tip with a chip from Racing Dynamics.

Is there anybody from Racing Dynamics in this forum?

it does indeed have a safe mode. it engages when it sees something wrong. it will do it immediately if it is a coding problem.



at first i thought it was the same thing. then we managed to nail down that it was only happening after 6 minutes, which is the built in timer for odd faults like knock sensors.

Quite q complicated little box.

YUP - the tip has a second unit that changes everything too. the tuning for that was very different than the manual, which is why i didn't want to get into it in the first batch. i really wanted a cold and hot season on the first batch, before i started going outside the box with variations like that. it just didn't work out that way, but that's another story for another day................



anyway, i'm sure we'll get to the bottom of durtkillon's problem. we just need to spend a bit of time on it. i may have to pop out there and hook up my durametric if he can't get one going. i need to see how many knocks it's picking up and where, assuming of course it wasn't just the sensor, which is known to fail, and is right there where it is in harm's way when you are installing the kit.
