    Megasquirt thread: Megasquirt and You

    Once you get the car running and feel comfortable it, I would suggest trying the latest pre-alpha code. There have been a lot of really trick updates worth taken a peak at.

    Arp headstud free spinning

    depending on the condition of the tap, gunk in the block, a cutting tap should never be used on already threaded holes, especially the head bolt ones. You'll cut and make the threads thinners. I've always borrowed a friends thread chaser witch just cleans the threads and doesn't really...

    1JZ Keeps on giving lean code even though its not running lean.

    As hvyman said, it could be as simple as an oxygen sensor, or even a screwy coolant temp sensor. On the ecu side of things, say your exhaust manifold is cracked leaning out the exhaust so the oxygen sensor is picking that up and adding fuel. Once you have reached the internal trims of...

    Clutch for Tremec T56 Magnum + JZ

    Depending on the adapter ran, you can run any supra clutch. Just call the maker and have the disc splined for the GM tranny. The clutch that 525gte is running was bought for my car, then I changed directions and need the triple in the link. He has a Stage 4 or 5 from Competition clutch...

    T56 swap onto 2jz pics

    I called Exedy direct. They sent me a Triple pull style for stock 2jz setup, with discs made for the GTR. The spline count is the same, just called out in metric for the GTR.

    2jz, 26psi, MS3Pro, Wiseco 9.5-1, K1 rods, S1's, 6466 divided .84, staged injection with 1200cc secondarys on A1000-116 race gas. Pull peaked at 26psi then dropped out to 25psi. AFR's are just a tad rich but a safe street tune. Cars a hoot to drive, and with the antisquat suspension I have...

    Changed wastegate and spring. now it over boosts aem ems v2

    You may have said in your other post, what kind of boost control are you using? AEM? open or closed loop? If open loop your DC numbers will be really low to only get 2 more psi, plus your ramp in, if set higher will mostly likely need be dialed out. Did the new gate get rid of creep...

    I'd be more than happy to send you an old Msq with that stepper motor. I've switched to a pwm style now.

    I ran the 6 wire IAC to for a bit, also with the 12v wires cut. Worked good.

    Just got back from the Dyno. Very happy with the results for a daily driver.

    volume differences between GTE and GE oil pumps (i know the sensor difference)

    I dont know volumes, but can tell you there is quite the difference in gear size.

    1jzgte Aem EMS question

    It should, just need to make sure theres enough ignition and injector outputs for the style of injection you want to run. Look at aems pinout of it, and see if theres additional injector outputs, and the amount of ignition outputs. You might be able to run sequential injection, but wated...

    Boost Creep Problems

    you can do that, just turn the regulator down to 20psi or so and you wont have any trouble. check to make sure the gate is opening fully and the valve stem isnt bent. What size is your main exhaust? I know you said you had it tuned, but how does your timing map look? high egt's from...

    Boost Creep Problems

    I have that same header with the same wastegate that 525gte has. I have a bit larger 6466 Precision turbo with .84TS T4 housing, when I had my small spring inplace, I could maintain 8psi to readline with zero creep. Id look around at other things and maybe header backpressure at the given...

    Megasquirt thread: Megasquirt and You

    Thought I would update and let you guys know what Im trying. I already posted that Im staging in E98 to mix E70 in the combustion chamber, but its mixed with 92 pump rather than 87 pump like normal E85 so timing can be close to a true E85, but I was looking for more resolution in rpm and...

    Megasquirt thread: Megasquirt and You

    Thats great news. Have you gotten anywhere with street tuning? Hows the 6262 feel on that motor? Personally I would run knock control. Can be a bit tricky to get setup, but overall pc of mind. Im running the Bosch wideband sensors and without any knock correction, or able to log knock...

    Cooling configuration doubt

    Its actually the other way around. The steel pipe that is down low is suction from the waterpump, so water is fed from the upperneck to the turbos, then returned to the pump via the lower tube. That tube also provides the suction for the heatercore, oil cooler and iac motor.
