Was reading the X1 files and it says wrap the inlet seals with teflon tape when fitting. Has anyone done this ? | ||

Not something I would choose to do. I have had good luck with O ring lube ( a pink paste, comes in a tube); a very light coat allows the mainfold/head/seal to find their happy place. | ||

I used WD40 for my throttle body when I installed that. But you're talking about the manifold-head seals, right? | ||
| Snowbees |
yeh, head to manifold, just wondering,just in case i decide to change seals again. my afv is at 117%,so today i sprayed wd40 on them at 2000rpm with no noticable difference, so maybe its not the seals. One other question, does the ecm add or reduce fuel with a hot IAT sensor, mine is located near to the engine, so was considering moving it to behind the headlight cowl to help add a bit more fuel and therefore reduce the afv. | ||

"does the ecm add or reduce fuel with a hot IAT sensor" Here is a partial answer per the Cold Start Enrichment table (which of course relates to engine temp not ambient) -10 180% 22 130% 65 106% 130 102% 170 99% 210 96% 260 110% But in general I don't think the IAT plays that big of a role in fuel delivery to cause 17% reduction in fuel. I could be wrong. (Message edited by kalali on July 09, 2010) | ||

Regardless, I would move the IAT to a different spot where it can measure ambient temperature as closely as possible. | ||

"O ring lube" would KY jelly work?  | ||
| Kalali |
"..would KY jelly work?" I can't see why it wouldn't but you gotta make sure you wipe your feet when going from the garage to the bedroom to get it... | ||
| Snowbees |
i have moved the IAT so we will see what the result is on the next run before i start spreading Ky all over the place ! | ||
| Akbuell |
KY might work, but I would have two worries?. One, will the KY formula 'attack' the seals and cause them to degrade? And two, will the KY 'cook' into something brittle due to engine heat? Just wondering. | ||

Use a lube like Sil-glyde on seals and manifold. And the 117% means it was adding 17% fuel. So somewhere in your learned fuel are you have a lean spot. | ||

I have always used petrolium jelly(KY)on my intake seals and any seal I install. Even use it to pop a stubborn bead on a race tire when the RU- Glide's not working.  As for degrading the seals, mine have been in(knock on wood) for 5yrs. and their holding up just fine. | ||

"And the 117% means it was adding 17% fuel" Yes i know, but whats the cause, first was seals so i sprayed them with wd40, no change in rpm. it has a new lambda, fuel pressure 49 psi, and i replaced the injector o rings, no change. its a race ecm and exhaust with a foam filter, maybe the maps need adjusting. Going for a spin today, i will see if the IAT relocate has made a difference.  | ||
| Snowbees |
well, just done 100miles, got back and checked afv with the IAT behind headlight cowl, 111%, so a 6% reduction. that i can live with but it would be good to see it stay at 100%. | ||
| Kalali |
Don't get too hung up on trying to make it stay at exactly 100%. As long as it stays within 95-105 range you should be OK. Mine fluctuates between 100-105. If you are really anal about keeping it at 100 (assuming no leaks, etc., ) you could experiment by adding fuel (if AFV>100) or reduce fuel (if AFV<100) to your maps in the Closed Loop area. You could set your map display to show you the Closed Loop area; roughly the area within TP=25-40 and RPM=2500-4000. Do you have Race ECM or Race maps? | ||
| Snowbees |
Its a race ecm, not too bothered at the moment, It still runs well. 111% will do, at least its adding fuel across the maps. I'll stick some blue james seals on it if it gets any worse, but i did'nt detect a leak in the ones on the bike. I'll get it on a dyno this winter, I might get round to sticking a carb on. |
