Why are you running a MAFS with your megasquirt?

The base tune on the DIY website should get you started once you scale the injectors.

As far as I know, yes. As long as its just at idle, It shouldnt hurt anything to test at idle.Hopefully you left enough slack to just swap your COP connectors around. I am guessing you are going to know instantly if this solution works because she is just gonna purr... Once you get your car tuned, s...

The distributor spins backwards (counter clockwise). As far as I know MS firing order just goes in order of A-B-C-D, etc. So, I think you should be set to A-1,B-3,C-4,D-2.

Hi,
I run the MSPNP2, but not with COP setup.

Just to cover the bases, you set the base timing (with fixed advance to whatever you decide, I used 15 deg)?
And you are 100% sure that your firing order is correct?

Hi All, I wanted to share my Dyno/Build with everyone. Namely because it was the kind of info I was looking for when doing my build but I was not able to find. Generally, the two groups on here seem to be the ones really pushing the power envelope for serious racing or the persons looking to “Turbo ...

I filled my mounts with Flexane 80. They still have some vibration insulation properties vs solid. But they keep everything nearly motionless even clutch kicking in 3rd/4th gears. Plus, Its CHEAP compared to aftermarket mounts.

I think you can just buy some Toluene at the hardware store and do exactly the same thing. It will almost definitely be cheaper. Just make sure to keep it off your paint.

HI, I am at the very end of my build (At least financially speaking). My engine builder suggested that I have the piston skirts coated with TEFLON due to some minor scuffing caused by the poor quality of the previous owners build. Why anyone would spend $500 on pistons, $800 on rods, and then skimp ...

My preferred method by myself is the olde faithful lay on the back, tranny on the knees, try not to slip and drop it on the family jewels method. My car used to shred 3rd every couple times I went to the track so, I only got fairly proficient at this method.

I think the relief valve just vents internally back to the non pressurized (oil pickup) side of the pump. Meaning, it would just be pumping in a very small circle without going to the oil filter or back to the oil pan. If you want to verify the oil pump is pumping, I would just put your dowel or wha...

I just had a very similar experience. Everything was fine then all of the sudden, ZERO oil pressure. Like you, I noticed immediately, so my motor suffered no ill effects. Mine was due to a faulty relief valve. Even with the filter completely off, no oil was coming out. Even after I disassembled the ...

Just out of curiosity, did you confirm if the clutch is uncoupling properly? I would put the car in gear, depress the clutch pedal and have someone try to spin the wheels (assuming you have an LSD). If it hangs up and tries to turn over your motor with the pedal in, you found your problem. I have se...

I did DIY cam gears to degree my 264's. My exhaust is spot on with cam card but my intake is off slightly. This was using a vice, punch, and hand drill. It is not for everyone but I like doing things myself. If they would have been off greatly, I would have coughed up the $150 for gears. I did esse...

I believe most people on this board who run this setup have already done this but just in case. You will definitely want to buy or make adjustable cam sprockets that will adjust your timing to a more appropriate 3 teeth +5 degrees. The DIY mod is very easy and if you already have your cams out it wi...

To set my timing, I just put a small alligator clamp with wire on the starter solenoid positive lead, put the key in the "Run" position, then touch the other end of the wire to your positive battery terminal.

Audacity has the ability to "Enable Software Playthrough". I am at work right now so, I can't tell you the exact command you will need to use. But, I think it was: Recording Preferences -> Transport Menu -> Enable software playthrough. However, this is software not hardware playthrough. So...

Thanks again everyone for sharing your thoughts on my car problems. I have seemingly already been through 2 Felpro's and still have leaks. As I expressed above, I am 99% certain that the problem as not with the HG but rather with either the deck of the block/head or a crack somewhere. Since, I alrea...

UPDATE: As expected, HG is still leaking after retorquing to 68ft/lbs. So, it looks like the motor is coming out for the 3rd time in 6 months. And the head and block are going in for machining so that I can run a MLS HG. I assume that the pistons have to come out for machining. Do the crankshaft, fr...

If you just want to see if the pump is primed and working, you can also unscrew the oil filter just enough so the gasket on the bottom of the filter is not touching. Then have your buddy turn it over for a few seconds while you are watching from below. If you don't have a handy bud, you can put a ju...

What does the PS electrical line do? Just idle up when it senses movement? Or do you mean you are not running PS anymore?

Thanks again for the help, compadres. I did not use ARP main studs because my engine builder (Who is a generally accepted around here as a Nissan god), told me that the extra clamping pressure from the ARP's causes the girdle to go out of round, necessitating the need to line bore the crank tunnel t...

I ended up following Airman's advice. Checked a rod cap, replaced the oil oil pump cover with one from one of my parts motors. Everything looks great now. It seems like even when the relief valve fails, it does not stick completely open. So, there was some oil flow. Luckily, I noticed the pressure d...

I'm going to see what they would do about custom, stripped, "racing" harnesses, so to speak. I'm only going to be needing the essentials - aka probably half the plugs in there. Thanks for the response! I know I don't want to use my stock one anymore. A brand new harness just sounds so nic...

Thanks again for all the great suggestions! I guess since there is basically no time difference in attempting a re-torque to pulling the head for re-measurement and potentially having to pull the motor apart to have the block decked, I will give this a go as a hail Mary. Since the coolant bubbles ou...

Thanks for the responses guys. Although, they are certainly quite different opinions. Airman, I will certainly look for HG deformation when I pull the head. Thank you for the pic. My experience with blown gaskets has been that its usually much more difficult to find the failure mode. I am guessing t...

Hi All, I have air entering the cooling system via the combustion chamber around cylinder 3. Comp#'s are still within spec and are all within 1psi. The motor has a very recent rebuild with forged internals, etc. My head has just been resurfaced and I am using a felpro gasket. When I installed the he...

That is soo tempting. It would be nice to know I am not chasing phantom electrical gremlins every time there is a problem.

I wonder if they can do it with different injector and MAFs plugs for the same price.

I am in the same boat with Martin at Enthalpy. He has been a huge source of information and always replies promply. I am also running the E85/93oct Dual tune. My car is still running lean but Martin has been working with me to find the solution which I rather suspect has more to do with my fuel syst...

I have never had it on the dyno so, I could not give you any firm numbers. I am also still dialing in the tune so just running on W/G spring at the moment. It is worth noting that I rebuilt the turbo with a Kinugawa 8 fin wheel and it builds boost crazy fast now. It feels better than my GT2835R did ...
