  1. 2G Camshaft degreeing help

    Are you using solid lifters while taking the measurements? If you are using the normal hydraulic lifters, they will bleed down over time from the spring pressure and give you an inaccurate measurement. It sounds like that is what is happening when it changed from 0.040" to 0.047" while...
  2. Oil ventilation

    The vacuum from the intake pulls the water vapor, blow by, etc out of the crankcase from the valve cover.
  3. How to come up with a compression ratio?

    Hey,Static compression ratio is the ratio of the maximum to minimum volume in the cylinder (volume when the piston is at the bottom of the cylinder versus volume when it is at the top).This can only be changed by changing the physical components of the engine (crank throw, rod length...

  6. ECUflash Excessive knock and crazy backfire

    Do you have any means of posting the tune that is currently in the car for others to look at for you? Perhaps you can get your tuner to email it to you?If not, one thing that comes to mind is there are two separate timing maps in the ECU. A high octane timing map and a low octane timing map...

  10. 2G Ceddy mods and P0446

    Sorry to hear. More than likely its bricked. I believe its from the connector and voltage.Years ago when I first started messing with ecuflash, my laptop locked up and got blue screen of death in the middle of a flash. I shit a brick cause my car wouldn't run at all. I was able to reflash it...
  11. 2G Ceddy mods and P0446

    Its been a long time since I did this, but I believe I replaced the ceddy mod hex and xml files with the ones in the zip file that included the emissions tables. You should compare them, just to make sure. They should be the same until the end, then there is code written that creates the...

  13. Resolved injector misfire

    I tried to move my wiring harness as little as possible when I switched injector #4 with #3. When I made this switch, I started the car and held the RPM's above 3,500 until it misfired. When I checked the injectors, #2 (which wasn't touched) wasn't clicking, hence my confusion.This I am not...

  17. Would this be a good product to tune with?

    There is always this debate between flashing and ECMlink... just a breakdown:ECMlink:More upfront money: need a eprom ECU or one that can be converted to eprom (money for the ecu plus money to have it converted), plus buying the hardware and program itself.(Your 98 ECU CANNOT be converted...

  20. ECUflash EcuFlash Tunning Map Suggestions

    Just giving some basics. AFR ratio is Air to Fuel, for example; Parts air : Parts fuel. "Rich" is a low number, 10.0:1, meaning 10 parts of air to 1 part fuel. (less air for the same amount of fuel) "Lean" is a high number, 16.0:1, meaning 16 parts of air to 1 part of fuel. (more air for the...
  21. Manual Rear Differential Noise with Solid Aluminum Bushings

    hey guys, sorry I haven't responded in a while.I ended up taking two rear diffs (auto with LSD and manual without LSD) and made a manual with a LSD.Swapped it out with the one in the car and the noise is very minimal now. Like exactly what I would expect with the solid bushings.I have the...
  22. ECUflash black box tuning help

    When I set the base ignition timing on my car, I used the actuator feature in evoscan to set the timing. It's located in the bottom right of the program. I had to select the correct ecu but after some failed attempts, it did work.It's obvious when it does work, as you hear a change in the cars...
  23. Manual Rear Differential Noise with Solid Aluminum Bushings

    I couldn't remember what oil was in the diff, so I changed it out with some basic 80w90 to be sure (based on TRE's site) and the noise is the same or slightly quieter. I have two spare rear diffs, one auto w/ LSD and a manual w/o LSD. I plan on opening them up and combining them to make a manual...

  27. Questions for Justin...

    It's stock. I needed a new BOV anyways so I just purchased a new NGR unit, so hopefully that solves the problem. I'll update my post with results and the video once I swap it out for future reference of other users.Thanks again
  28. Questions for Justin...

    Hm. I didn't even think of the BOV. I did just put on a 1g bov on because my greddy type that stripped out the adjustment screw so I replaced it.Is there a solution to fix the bov if that is the issue?
  29. Questions for Justin...

    Justin,I have a 16g that is making a high pitch whine at idle. Blipping the throttle makes it go away for a second but it comes right back. If I increase the throttle steadily, it just gets louder.I'm guessing this is a sign of a turbo on its way out?Is has very little / no shaft play...
  30. 2G Early '95 Vented Rear Brake FAQ (Discussion/PN)

    This may be a pointless question, but since the parking brake is incorporated into the inside of the rear rotors, has anyone verified that the vented rotors are dimensionally the same on the inside as the non-vented and will work? I'm looking to do this swap and wanted to ask before ordering parts.
  31. Will a more restrictive air filter help boost creep

    Hmm..... I never thought to look at it like that.It wouldn't solve the problem, but it may work as a bandaid fix. If you restrict the amount of air coming in (smaller filter, pre MAF) it won't fix the creeping, but it MAY limit the amount of air the engine is pulling in, limiting your max...
  32. Questions for Justin...

    Thanks, I've seen those and definitely considered getting one, but I thought I read that the need a slight angle machined on the turbo flange for block clearance and that the bolt holes were 1/2" off on the turbo flange making the ports not line up. If that specific one has reviews showing...
  33. Questions for Justin...

    Awesome! Good to hear. I've been searching for a turbonetics t3 manifold and they are kinda hard to find. I found a dnp t3 manifold for $150 but I the only thing I read abou them with fitment is with a bullseye .70 t3 housing for a HX40, which is a lot larger than the HY housing correct?

  36. 2g/7bolt front case picture/diagram needed

    Bump cause this is something I was trying to figure out too and this helped tremendously! Maybe a moderator can change the title or make this easier to find for future use. I searched "front case bolts" and this was on the 4th page. Either way, its way old but still helps!
  37. what's the most limiting in flow/HP?

    That is absolute pressure, it doesn't account for the atmospheric pressure (14.7 psi) so the maximum boost pressure reading is only about 29 psi of boost (43 psi-14 psi).GM MAP sensor identification information 1 bar 2 bar 3 barThat's why if you want to run 30+ psi you need a 4 bar MAP...

  39. Has anyone seen this center dash bezel before?

    I looked it up in the owners manual a while ago. They have some special name for it, but essentially it allows those two center vents to always be open, no matter what setting the vent selector is on. The top selection with the blue background means its always open, and the bottom with the white...

    Sorry, just checked this thread again. I learned most of the stuff I know about evoscan/ecuflash (and I still consider myself a newbie at tuning) from this youtube video series:Intro to EcuFlash - 1 of 16 (How to Tune an Evo) - YouTubeI watched it a few times to make sure I had an idea of...
  43. Evo scan logs..view them MS Excel?

    For the fuel cut, I raised the load limit and left the time alone. From the factory, it is set to 200 load for 1000ms or 1 second. This means if the ECU sees more than 200 load for longer than 1 second, fuel cut will happen. If you increase the time, you are essentially shutting off a very good...

  46. Evo3 16G! How to make it sound louder spoiling?

    To answer your previous question, fuel cut is purely based on load and time. With ecuflash you can change these values, to either a higher value load, or a longer time.Fuel cut is the engines ecu cutting the signal to the injectors instantly after the car exceeds the predetermined load value...
