91 TSI/AWD
 

Hey guys, just picked up a TSI/AWD from another member here on the board, have had zero problems, changed the oil, buffed and waxed and shes ready to go! Only real mods are a 16g and an eBay BOV....

It did pull past an 02 WRX wagon (Exhaust only) last night.. . :Banane55:


I do have a turbo back exhaust (all eBay...) arriving in the next day or two, that with a full tune up and some TLC, it will be a great driver.

Re: 91 TSI/AWD
 

The exhaust showed up today, at least the o2 housing and down pipe. Catback will show up when hell freezes over..... The build quality is meh. Its eBay though, so I cant complain.

Some more maintenance before modifying anything. Did Transmission, Transfer Case, and Rear and fluid changes. I also got a good timing belt cover from my buddy! No more busted one. Still gotta fix the oil leak on the valve cover and turbo return line....

Smells as good as it looks :/

Re: 91 TSI/AWD
 

Maintenance is getting closer to done, new valve cover gasket, plugs, and wires for today. I didn't like the green machine scheme on this burgundy car... So it will be black, gotta find a spark plug cover thats not 10lb's of diamond plate...

The car runs smoother than ever, doesnt burn oil at WOT anymore?... The old gasket was leaking everywhere. Still have to address the return line leak, then it will all be good.

Re: 91 TSI/AWD
 

I have all the exhaust now, and the car was tinted last night. Just going to let it sit and set up in the warm garage for a few days.

Mmmmmmmm Captain Coke.... All the exhaust on, only had to modify the down pipe. Other than that, hits fuel cut @5000rpm, and the open waste gate sounds good... Tint is dark enough, I'd like to remove the smoker vents though. I also still have to fix the oil leak on the turbo return line. I have gaskets for it already.

Re: 91 TSI/AWD
 

Nice Exhaust! Love the o2 housing with the external dump pipe. Must scream! A little bit more engine bay clean up and youll have a way nice ride both in and out! Pressure wash it maybe? Hope to see it driving around the streets some time!

Re: 91 TSI/AWD
 

Thanks man, are you from the msp area?

The bay is pretty grimey :/ here and there. mostly undercarriage gunk though. The open dump sounds cool to say the least. Lots of surprised looks after a run with any car lol.



Anyone have a suggestion on what to do about fuel cut? I've been talking with a few buddies and both suggested a Walboro/TRE fuel pump off of eBay. Any other fuel items that could be addressed as well?

Re: 91 TSI/AWD
 

fuel pump, injectors and dsmlink to tune it with.

Re: 91 TSI/AWD
 

Fuel cut has nothing to actually do with a lack of fuel, it happens when the ECU sees too much airflow and it assume the wastegate setup has failed and the car is overboosting. You should get an upgraded fuel pump anyways though. The real fix for fuel cut is to turn it off in the tune, you can do that with DSMLink or an Eprom chip.

Re: 91 TSI/AWD
 

Just do a fuel pump, 550cc injectors, and 2g maf. it will put a smile on your face. Is that exhaust loud?

Re: 91 TSI/AWD
 

Thanks for clearing up that misconception! Makes perfect sense. I'll look into dsmlink after I finish maintenance. Will the 1g MAF read enough air with the 16g @ 15psi? I believe my roommate has a 2g MAF. Also, are the stock injectors able to support that much over factory boost?

The exhaust sounds really smooth when idling/cruising, the wastegate is pretty loud, so its hard to really tell how loud the exhaust is at WOT.

Re: 91 TSI/AWD
 

I always wondered, how do those fuel cut defenders lie to the computer without any ill efects?

Got two good front seats form the local pick and pull. Old passengers seat is for sale in good condition, pm me. Lots of carpet interior detailing got the car pretty clean.

Re: 91 TSI/AWD
 

makes me regret buying a bike. i think its time to get back into the dsm game. and its only been a month. looks clean nice pick up. hope it treats you well

Re: 91 TSI/AWD
 

Get another one! I've seen a couple good AWD 1g projects in the cities for a decent price.


Next up is brakes. The rear brakes are starting to wear out, the e-brake cable doesn't work either. Maybe there is a good, reasonably priced upgrade I can do to do while I'm at it?

Suggestions?

Re: 91 TSI/AWD
 

On cars like a Toyota Supra or MR2, they have a MAP sensor and a MAF. The MAF is used for primary fueling, ignition timing, load cal, etc. The MAP sensor is just used for stuff like reading boost and checking to see if EGR is working, so devices like the HKS FCD just clamp the max voltage going from the sensor to the ECU at a voltage right below fuel cut would hit. The MAF still reads and adds fueling.

On a car like an SRT that uses the MAP sensor for everything, if you clamp it at say 13psi to avoid hitting 15psi fuel cut, then it will start leaning out when it goes above the clamped voltage/boost level.

On a DSM that only has a MAS for eveything, it will start leaning out above whatever airflow they clamp the signal to the ECU at. It's a hack... Most people used to get around fuel cut on DSMs by putting in too big of injectors and lowering the reported airflow to the ECU via a piggyback like the SAFC. There is no reason you need 550s with a T25, 14B or 16G on your typical pump gas gas, except to be able to fool the ECU away from fuel cut.

So there can be ill effects.
