  1. LS-1 MAF translator vs ARC-2/ VPC

    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.
  2. LS-1 MAF translator vs ARC-2/ VPC

    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...
  3. LS-1 MAF translator vs ARC-2/ VPC

    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?
  4. AEM Stand Alone <===Need Input/Opinion

    What makes you think that the price you quoted for AEM comes with all you need? You will still need to buy the optional sensors to convert to MAP.
  5. Aem Ems

    The reason is simplicity. Nothing is more simple as turning 3 knobs. The best of all, it works.
  6. 60-1 users must read

    30-33psi on pump gas with zero knock. Am I missing something here?
  7. 60-1 users must read

    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 ;)
  8. General 1G Fuel Question

    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.
  9. injectors

    Hahn 625 injectors are really 550s but capable of running higher duty cycle.
  10. ETA32 Should I be dissappointed in my Dyno numbers? Also, fuel ?

    Sorry if I misunderstood you ;)
  11. 60-1 users must read

    When did I said anything about reversion? Read my post carefully.
  12. 60-1 users must read

    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.
  13. Injectors

    Err, aint you forgetting something? Should be: 450cc/min * sqrt(36/43) = ~412cc/min.
  14. ETA32 Should I be dissappointed in my Dyno numbers? Also, fuel ?

    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...
  15. Big28 Killer Times

    Someone need to hijack this thread.
  16. Hahn super 20g turbo

    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...
  17. Hahn super 20g turbo

    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...
  18. O2 trim vs. O2 voltage

    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...
  19. X-mas Texas Style

    Sorry for the hard question.. LOL.. OK, here is an easy one, why T3 comp housing and not T04E?Btw, check PM.
  20. X-mas Texas Style

    Why 46 trim? Give us some review on the turbo once you get it installed. The turbo look decent nevertheless.
  21. injector size and effect on Air counts

    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...
  22. injector size and effect on Air counts

    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.
  23. Dynoed Today (AGP L2R)

    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?
  24. Stock fuel pressure readings, before re-wire.

    What is your base fuel pressure? Remove the vacuum hose from the FPR at idle and look at the gauge.
  25. AFC or GCC with VPC?

    If you like plug and play, then GCC is your best bet. If you not mind soldering, do the VPC/S-AFC combo.
  26. VPC dipswitch settings for a 2G?

    Leave the dip switch setting alone. They are meant for debugging purposes from what I've heard.
  27. O2 trim vs. O2 voltage

    Fuel trims dont mean sh!t to ECU in open loop. ECU just use air mass (airflow, iat and baro pressure) to determine IPW.
  28. Tuning a FP Green w/ AFC

    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...
  29. Apexi S-AFC Version 1 vs Version 2

    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...
  30. AFC question

    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...
  31. What sensor is this?

    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?
  32. Vpc Help

    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...
  33. VPC Chip/Injector Mismatch?

    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.
  34. Vpc Help

    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.
  35. Tuning a FP Green w/ AFC

    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...
  36. How far has a 6-bolt/95 pistons setup gone?

    Hmm. When did Buschur has a 1G RWD? :confused:
  37. Shutter Box, how the hell.....?

    A fast spooling turbo and "no lift shift" are two different things.
  38. Dynoed Today (AGP L2R)

    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.
  39. Adjustable Constant Intake Air Temperature (Long)

    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...
  40. maxing out injectors

    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...
  41. maxing out injectors

    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?
  42. to dump or not to dump?

    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.
  43. Question on Ball Bearing Turbos and Stroker Engines

    With added torque and quicker spool means you'll be breaking more trannies.
  44. Symptoms of a bad map sensor?

    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.
  45. Advanced Tuners Please Enter - Tuning Questions

    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%
  46. E.T.s and MPH in the 1/4

    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...
  47. Indy Race Core & TD06 20G

    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...
  48. Pocketlogger / datalogger what's the Diff?

    What are you talking about? The problem is not with the laptop or Palm, it's OBDII on 2G. For 1G OBDI, I get 55+samples/sec on the pocketlogger.
  49. evc iv install

    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.
  50. No joke, i am building boost in Nuetral!!!

    No joke, you paid $40 for a bleeder valve type boost controller???
