I would like to hear more from people running the MAF w/ blow through in a turbo application. Seeing in excess of 300F on the intake track is not unheard of and how that is going to affect the MAF and tuning.
The other thread on 3.5" MAF and larryd was saying about 3.5" MAF and I've also read it can be used as a blow through mentioned everywhere in the posts? FYI, 2G MAS is good to 2600-2700hz before it start losing count. How many here have maxed out a 2G MAS and see it lost count? How is hotwire...
Some pictures are needed because I am still unsure what setup you guys are talking about. When did we have a 3.5" IC pipes for 3.5" MAF blow through application? If you use it as a draw through, what's wrong with a 2G MAS?
40psi may sound too much for you but the Supra in town at ARD is running 40psi on juice with a T88.They are building an AWD with T66. We have to see how that thing spool on a 2.0 ;)
Make sure the wire tap for power on the diag. port is still connected. Most of the time, it got lose and you wont get a connection. Also clean the connections on the palm to the wire.
There are some things call "race gas" that will counter most of the problems he mentioned. Besides, that turbo push so much air you dont need to run high boost on the street with pump gas.
For those that think when you have 660 injectors, you should lean it out to -50%. This calculation is WRONG. It should be around the ballpark of -32%. Even -32% is just a ballpark figure that should be taken with a grain of salt. Depending on your base fuel pressure and your other mods (such as...
Check out turbonetics website on the comp maps. Read them and understand them. The maps are T04E which means they tested flow in T04E housing?Instead of going through a bunch of formula and physics. The bottom line is you want a CW that is capable of maintaining boost level you desired at...
A 50trim to 60-1 will be a better match for the TD06H IMHO. The reason for such a big TW is to reduce the PR between the intake and exhaust. If your PR is less than 2, then you would be better off with a smaller wheel to reduce lag. If the PR is greater than 2.5, then a bigger wheel will allow...
O2 not cycling at idle or part throttle is not a good sign. With 720s, you should be running dead rich but it seems to be starving for fuel. This is what I will do:
1) Fix the boost leaks.
2) Check fuel system.
3) Change fuel filter.
4) Change O2 sensor.
5) What is your base fuel pressure...
The hz count from the MAS would remain constant if everything remain equal dont you think? Injectors size has nothing to do with hz count. Besides, the airflow you saw from the AFC is unmolested number. You lean it out by modify THAT value the ECU is seeing. If you are talking about the airflow...
18% is a ballpark figure to start from. Obviously every car is a little different and so is the base fuel pressure. Start with 15-18% and rich/lean things up from there.
LOL.. You dont ground the CAS but ground the ECU from controlling the ign timing. Everything need to be referenced to the crank. How does the ECU know where the pistons are at without the CAS if you ground it? So, it's just going to fire the ignition by guessing?
When you talk hz count, you have to consider rpm. Running 22psi at 5500rpm may yield 2100hz while 22psi at 7krpm may yield 2300hz. The higher you rev, the more air is needed to maintain the pressure so it should be no surprise here.1G or 2G ECU works the same. More airflow means you have...
Personally, I go with the Blue screen S-AFC. It has the graphical mode that you can use to check if you have MAS overrun (1G MAS mostly) that you cannot see with a logger. Also, you can tell what is the max hz, rpm, throttle position, etc with a press of a button.When I misshift at the...
S-AFC is not only for the bling factor. It has a bunch of features that probably wont get it wtih the AFR. Although there are 8 adjustment points, they can be configured to at 500rpm increment. For instance, you can do 1000,2000,3000,4000,5000,5500,6000,7000 or any other rpms that you want them...
Why are you double posting? It does not look like a sensor but a valve. Someone already mentioned that in the other thread. Why dont you try pressure it and press the plunger?
I cannot tell for sure without going through everything to make sure the installation is correctly. The wire harness is done properly. The MAP and IAT sensors are working. VPC manual does say how you can test the MAP sensor. If you are sure the wiring are all done properly, then you should...
Nobody can tell you for sure if it will work. You just have to try it out yourself. I would suggest you to get a 450 chip unless you plan on running 660s soon.
Did you put the chip in correctly? If you have it in backwards, there is a chance the chip got fried. You have to line the notch on the socket with the notch on the chip.
Too low of aircount is not always a good thing. When the aircount get too low, the ECU advance too much timing and it become more prone to knocks.When my old turbo failed on me, I was only getting around 1200hz. Even at WOT, the ECU gave timing like I was doing part throttle with 30+ degree...
Nice numbers Larry. I am sure there are 101 reasons why the car wasnt up to your expectation. Work on your issues first and slowly eliminate the problems you have. I am sure you will see better numbers when you fix the problems.
If I understand you correctly, you meant replacing the IAT with a 10k pot? You cannot just leave the one end open per se or you get an open circuit.Beside the point, adding 10k pot in series with the IAT will not change the temperature range too much. You can look at how a VPC does their...
People has done it all the time. Not many of us will see insane boost level of 40+psi so I dont see any problem. Besides, at the pressure, the *normal* pump may not be able to keep up with the flow.The stock ECU has a limitation of ~1.7ms at idle so you would see a problem if you touch the...
97% does sound kinda high for IDC. Bump the fuel pressure a few psi and lean it out. Most people like to keep it less than 85%.Btw, how much boost are you running?
The welding is the worst I have seen thus far. I hope it's not mandreed you bought from. His O2 eliminator has so many leaks it takes more $$ to cover the leaks.
The manual states how to check if the MAP sensor is working correctly. You can use a bicycle pump to pressure the sensor to see if the voltage are within specs. I know at atmospheric pressure (gauge pressure at 0psi), it should read around 1.74v.
i dont know if my setting is worth mentioning since I am still tuning with this 550 chip. Currently, here is it:
Gain - 7 o'clock
Response - 5 o'clock
Hi setting:
1k - +3
2k - +2
3k - +1
4k - -2
5k - -4
5.5k -5
6k - -5
7k - -5
Lo: 25% Hi: 40%
ET is driver dependent. Better launch would almost guarantee better ET (if you dont screw up along the way) but trap speed is how much power your car is making. Usually trap speed is pretty consistent +-2mph but ET will vary widely depending on how well you launch and drive down the track...
You want the 90 degree elbow welded to point to the driver side. Ken's IC pipes will work but it's tight fit because it will rub against the front motor mount. You can clock your comp housing to the front a little to clear (if you have external wastegate) but I said it's easier just to weld a...
You should hook that up to the compressor boost source. That signal is used to open your wastegate. The #1 is used for getting your boost reading so it knows when to control boost.
