Mark,

I think there is a misunderstanding. It is the cooling fan on the decklid seems to be hitting the top of the maf e.g. the bottom of the fan housing where the plug for the fan is connected?

We need to get Todd to pull back the timing a bit, because the car is running rich. We haven't driven the car yet because of these two issues. Just had it running for an hour in the garage.

 

that's what Im saying... I dont have it... and nor do 99% of similar set ups...
that fan was to prevent the stock air box/filter from getting hot... now you dont have it anymore... so its really not needed.. once I saw on relocated to the left... cut you have to get creative...

dont break that maf sensor...
pressure test the car... you should it it from the Y pipe... if you have a post MAf boost leak the car will run wacky ... and idle bad

 

Okay Mark, we will get creative and move it to the left. We cannot see a leak at the moment and have checked everything. The strange thing was that when we first started the car the idle v was at .56. Then this afternoon it ran better, and was at .44 which is what Todd said it should be.

We wait for Todd re the map, and then drive the car tomorrow to get the logs, and I will folllowing your running in procedure carefully - just get on the motorway and hit the cruise control and keep it off boost.

Thanks for your quick reply.

 

Here are some more pictures - so very close now.

 

make sure you have the resistor inline with the maf .. I think todd does that already...

 

I removed my cooling fan with the Proto intake and now I am getting overheat codes? Is this something that Todd should program out.

 

very curious about this project keep up the good work and good luck !

 

Really very good set up you got 996ttalot,i am working on to get there too

CONGRATS

 

My fan was removed w/ zero issues.

 

Hi Guys,

So we had the car out today on the road at last. The car is definitely running rich as we can see that from the logs.

We ran for many miles with the EBC off. Gradually boosting up to 0.7/0.8. Car felt fine. Back up on the ramps, checked everything out and all was okay.

Then back out again. EBC off. No issues. Then switched the EBC on and set low to 0.9 bar.

Car was running okay but then we hit an issue with the car pulling timing at just above 4k revs. First time it happened was a reasonably quick spool of boost. Tried it again but this time just very very gradually building the revs and as soon as we got to around 4.2k it starting hestitating again.

Back in the shop, and it turns out that the additional fuel pump is screwed. Making really bad noise. So that is it for today until we get another fuel pump.

What I noticed, in the limited driving, is that the noise from the intake is amazing. As my mech said when we were driving, it sounds like an angry chimpanzee who has just had her bad chimp taken away from her, when you come off boost.

The other thing is that even running at 0.7 bar, in 4th gear (tiptronic) it ran 4.4 secs from 60 to 100mph. That is not bad given I was not flooring it.

Will update when we get the new fuel pump, but need to get the logs to Todd to get a new map.

 

datalog Rpm, engine load, oxygen sensor actual value bank 1 or 2, and boost sensor of pressure... run a 3rd gear but show me the idle logs too... then just go and do a 2k to 6500 run full.... turn off the greddy...

I doubt its your pump... check the voltage while the car is running should be 13V and check the fuel pressure should be 3.8 or so at idle.. its easy if you have the guage with the correct connection.. its the line you hooked up to the 2nd pump...
they do make noise when running but that is not the reason for your "timing" issue.. actually your car is not pulling timing just probably running 10s afr... your timing should be around 17 to 22 degrees on full boost full load...

 

Well finally got the car on the road today and it was a mix of wow and then doh.

The problem with the fueling was the 3.8fpr. Replaced this and pressure was fine at 3.8 at idle instead of 7 bar.

Ran for many miles and everything was okay - ran the logs and the only thing was that it was running a little rich. So will speak to Todd.

Once we had checked everything out, we switched on the EBC. Ran at 1.08 bar. After the first 3 or 4 runs in 3rd gear, not mashing the throttle since it was wet, the tip went into emergency mode. Checked the codes, and there was about 10 codes. It looks as though the ATF got too hot. THere was no slippage in any gear, just that it came on.

So as I expected, I think the tip is going to be an issue. I spoke with 9ff this evening, and it looks as though a deal can be done to get the 996 tip box upgraded to their 800hp/900nm version at a good price. I am speaking to them on Monday to organise.

I am a little surprised to be fair. I don't know what awhp I would be running at 1.08 bar, but it was night and day difference to when the EBC was off. I cannot see how I could run at more than this without doing the upgrade.

We are going to stick an additional tranny cooler on the car on Monday, and see whether the problem is excessive heat causing all the fault codes. The gearbox drives fine, like I said e.g. switched off, reset the codes, and the car seems fine. I suspect it is too much tq that is heating the clutch packs, and then generally heating the transmission and throwing the codes.

I don't think I can do anything else but do the 9ff upgrade. I want to know what 1.5 bar will be like, because at 1.08 bar, it was sensational.

Anyone else get this experience with a tip?

 

Marksi,

One other question. When we got the fueling sorted, is it normal that the main fuel pump makes a noise. It is like a constant wine noise. Fueling and AFR were okay as we were monitoring whilst driving.

The pump in the back makes a noise. It's normal.

 

Thanks for sharing the infos.
