    ECUflash First Flashed DSM ECU! (98/99 Flashing FAQ)

    I'm betting you didn't wire the crank position input on the ecu to the output from the cas.https://www.roadraceengineering.com/1gcasin2g-waveforms.htm

    ECUflash First Flashed DSM ECU! (98/99 Flashing FAQ)

    The 1G CAS is able to provide the correct signals to run the engine on a 97-99 ECU, but you have to wire in the inputs from it to the ECU separately for the crank position sensor and cam position sensor to provide the signal to the right ECU pins. The 97+ ECU is a little more picky though if the...

    Street Build ITFLYS - 1Gina2G

    I've been away from tuning for awhile and I have limited experience using ECMLink, but I am curious, do you have closed loop fuel trimming enabled? If so, what's the minimum injector pulsewidth correction per cycle?I'm assuming you're using much larger than stock 450s.Might try locking into...

    2024 DSMtuners Challenge - payouts and rewards for class winners and record breakers

    I like the idea. I think maybe individual vendors might award monetarily to people who achieve something while running their parts. Even awarding a partial sponsorship for a discount on their parts in the future could work. Maybe you could also offer some special privileges or profile banner on...

    420A Hahn s16g with 8cm turbine housing?

    They also offer a 7cm housing, which would be better matched to a s16g. If you could find a decent used 6cm off of a 14b, that would imo be ideal for that compressor, but that's pretty unlikely to find.

    1993 evo

    Which Evo gearbox are you using? If it's an Evo 1 or 2, you need a 23 spline input 1.090 transfer case, Evo 3 you must use a 23 spline input 1.074 transfer case.All Evo 1-3 rear diffs are 3.909, no dsm used that ratio. http://www.vfaq.com/mods/Trannies.html

    2G Hard to get into gear when engine running

    I would lean towards throw out bearing too. I don't like reusing pressure plates unless I know for sure they're still good. Discs, same thing. I would rather replace it all than get it back together and find out it's not right and have to drop the trans again.

    So... are you asking for help?Looks like it has some potential. Congrats on the lucky score.

    2G Bearing sizes.

    You should mic out the rod journals to be sure, but that 1.00 is probably indeed the undersized amount in millimeters. Im sure you realize, but the issue with that much of a cut on the journals of the crank is that it will almost definitely remove all of the nitride case hardening treatment. I'm...

    How are my main clearances?

    I agree with Marty.You might try swapping the bearings in 1 and 5 and measuring again, but all of those values should be fine.
  14. Zack Huffman

    Have my balls already been removed?

    I wouldn't. I know a lot of guys will tell you to always pull the balls and clean it real good, but I am not one of them. Those press fit balls have to seal the oil passages that feed oil to the rod journals. You screw that up and you will weld a rod to the crank and window the block.Just my...

    2G Code P0340 weird issue

    If all the valvesprings are indeed sitting at the same height, you'll probably find at least 1 valve head snapped off and embedded in a piston. If you find a pair of valvesprings that sit lower than the ones on the cylinder next door, then there's a slim chance the bottom end might salvageable...

    2G Code P0340 weird issue

    I'd start with simply pulling the valve cover and inspecting. There's an outside chance that you just kicked a rocker off and you're smacking it around with the cam lobe when the engine rotates. However; usually it's a symptom of a bent valve when you kick a rocker. Also make sure you pull the...

    2g AWD won't move in gear

    Right?!!! Scary how similar it is. Almost makes you wonder if the neighbors cat got under your car and cuddled the turbo to get warm, but then threw up all of the dog food it ate out of the other neighbors trash can, and died there because it got its tail stuck in the rad fan. Because that's...

    2G 750cc injectors on 91 pump gas?

    You might be pushing the limits of the pump on a 255lph at 26psi running e85. Make sure the voltage to the pump is as strong as possible and make sure the fuel supply line is without restriction as much as possible. Otherwise upgrade the pump. When you turn the wick up, watch the AFR under...

    2g AWD won't move in gear

    I've had 3 full-face stock type organic clutch disk failures from wear and tear regular usage. In my case they all separated/wore through while I was making a low speed shift.

    General ECMLink vs Haltech Elite

    Typically "limp home mode" is reserved for OEM engine controllers in order to decrease likelihood of irreparable damage that costs them in big warranty repairs. Most aftermarket solutions will not worry about supplying you with a default safe mode. If you want a failsafe you usually have to...

    2G Single & dual stage MBC not working after rebuild

    I've not encountered an Evo 3 16g with an internal wastegate actuator set for less than 14psi. The stock t25, on the other hand fully extends around 10ish in my experience. An Evo 3 16g is just getting started at 10psi, most wouldn't want an actuator that low opening on a 16g.

    Oil pump seized

    Awhile back it was a popular thing to have the oil pump balance shaft turned in a lathe to remove the counterweight portion but retain the long shaft. This was done in order to support the pump better -as opposed to having a stubby shaft with much less rotational inertia.With aftermarket parts...

    1988 4g64 misfires and bad idle

    I'm not sure what to suggest except for maybe an adjustable fuel pressure regulator.And yes, you certainly can run an engine in open loop without feedback to trim the fueling, but I am surprised that it is set up that way from the manufacturer. Filters clog, injectors get dirty, pumps wear...

    1988 4g64 misfires and bad idle

    So if the catalytic convertor were equipped on this car, would it be located before or after the sensor?Without feedback trim, you'd basically have 4 injectors working like fixed electronic carburetors. Even carbs can be adjusted. I can't imagine a manufacturer denying that functionality on...

    1988 4g64 misfires and bad idle

    If it's fuel injected it will need to have an upstream oxygen sensor to run correctly. Is it possible that you overlooked it or that the exhaust has been improperly repaired? Do you have an ECU pinout for this car? The closest I could find was one for an 89 Galant SOHC, but it clearly shows an...

    Been lurking have a Few questions

    I would offer a little less than $2700 for this fwd, but I think it looks like a solid starting point. That wastegate and the tubular exhaust manifold probably both need replaced. What turbo is installed? Injectors? Which tuning solution? -It's been running on speed density logic, so it's either...

    1G restricter on presision turbo

    The answer is not straightforward, that's why everyone is telling you different things. What works on another car might be totally wrong for yours. It's all about the pressure at the chra oil feed. You want it below 80ish psi at redline. If you have no balance shafts or piston oil squirters...

    2g awd part hoarding

    ^ I think that's what everyone wants currently, -to pick the hard to get pieces out. There's probably not very much demand for a stock rebuilt awd trans otherwise.

    Got a few days to make a decision. Guns or Cars?

    My answer would depend on whether you have an adequate amount of firearms currently or not. I'd recommend a concealed carry-able sidearm and a shotgun at a minimum. Be able to defend yourself and your family above all else. It's a crazy world out there, so much turmoil and people are being...

    2G 95-97 vs 98/99 engines

    A 7 bolt crank will fit any 7 bolt block. That includes any displacement 1992.5 model year all the way up through the last Evo 9. Some of the later Evo cranks are significantly lighter. The blocks everyone tries to avoid are the 1995 to 1997.5 blocks. Any engine can crankwalk, but those are the...

    Top Mounted Manifold Love (4g64 Starion Swap)

    Archer fab also offers a top mount T3.I'd probably have a hard time choosing between ordering their OTS part or calling Matt Morrison if it were me. Matt's may cost a little more but would use better material and he'd probably guarantee fitment, whereas Archer's may have interference...

    2G Intake Manifold Sensor?

    If your stock boost gauge is always pegged when running, you have an issue related to the airflow measurement the ECU is seeing/using. This can be caused by bad boost leaks, a really large set of cams, or most likely, from a miscalibrated or non-matching MAS.The ECU uses only 2 things to...

    2G Stuttering- video for review - opinions please

    Yeah this just happened

    I agree with @rabenne. All at 135 is okay for dry and lower compression or loose ptw forged slugs.The leakdown test would be reassuring of the headgasket, but otherwise the only concerns I'd have would be the main and rod bearings. I think your idea of running some cheap high detergent oil...
  44. Zack Huffman

    Yeah this just happened

    In my opinion, the high-ish BLT pressure caused the diaphragm to overextend, especially without pressurized fuel under it. The diaphragm may have been well used and may have just had a weak spot, but it was probably inflated like a balloon until it gave out, at which point the engine was started...
  45. Zack Huffman

    Yeah this just happened

    Yep. BLT with 35psi into the FPR reference line and diaphram got stuck would be my assumption.

    1G Web cams should I run them?

    Those are a decent street grind, comparable to 262-268 advertised duration cams from other manufacturers. They don't have as aggressive lift as some, but you should still use aftermarket valve springs. They will give you more midrange and a little more up top with basically no sacrifice in low...

    20G Discussion: TD05H vs. TD06

    Buschur's variant is a TD05H turbine with a heavy 20 degree clip, which probably gets it within spitting distance of the performance of a TD06 version, along with the additional lag too.A TD06 turbine housing will not work well with a TD05H turbine wheel.
