Compression test done while warm. I see no reason to continue with a leakdown or wet test. 1-180 2- 185 3-185 4-185Any ideas what it could be? Definitely do not think its my HG. The engine runs very strong, no misfires or anything indicating oil or coolant contaminating the combustion...

Smells kind of sweet. I'm betting hg, but I will know tomorrow morning or this weekend when I can run the compression test. Any chance a leaking hg won't show up in that?The smoke is constant at idle. It will not start until the car hits roughly 170 degrees. Then it will start in small...

I am trying to troubleshoot this smoking problem. It was putting out a smoke screen at idle. I removed the intake from the throttle body so that is pulling air straight in and bypassing the turbo. The smoke went away until the engine warmed up. After the car warmed up, it started...

He probably lied then

Seems like the general rule of thumb is 1% increase for every 10 degrees you drop off the intake temp. Say you drop the temp from 110 degrees to 60. A 50 degree drop or 5% increase. Now lets say you are making 300 bhp at 110 degrees. 300 * 1.05 = 315 hp. 15 hp gain due to temp, but you probably...

I see you have an AFC and dsmlink. Why?Does it really surprise you that a t-25 can flow the same as a v-trim at 15 psi? If the t-25's discharge is sufficiently cooled and both turbos are producing the same intake temp and pressure, then they are going to flow the same amount. The bigger...

It would also be a potential for compressor surge. "IF" you could obtain positive pressure and maintain it in the intake, the turbo would not be up to speed, and this pressure would try to escape back through the turbo. In order to build up pressure in the intake you would need an insane amount...

No offense, but the 1200 hp figure sounds a bit outrageous. You don't need 1200 hp to beat 99.99% of cars on the street. I got a crazy idea for you, buy a fiero. Then get yourself a lambo rebody and a built 350, and then you can strike fear into the heart of a ferrari... hahaOh yea, just out...

I am having problems with my a/c working. I checked the 1st gen pinout on VFAQ. Apparently pin 65 connects to the A/C. Does this apply 12 volts or go low? I am not getting 12V on the pins for AC switch or AC Relay. Is this a common problem for the ECU? I keep looking for information on it, but...

I just noticed thats a huge amount of advance at idle. Stock the car idles around 10 degrees. It shouldn't cause any problems, but I noticed it quited the exhaust down considerable if the timing was lower. A high advance can make your exhaust louder.GVR4592, Megasquirt does interpolate...

Do you have a logger and knock sensor still in the car? I will post my table up later tonight when I get home for comparison. One thing, your column for 400 is useless, you will never idle under 400 rpm. You can get rid of the 400 column and add one to the end going however high you plan to rev it.

You will need a knock sensor from a turbo model. Are you going to make your own harness or are you using a turbo model harness? I am a little confused on what exactly you have available. I am assuming you are just taking the n/a motor so you can have a built motor and turbo it, correct?

NO, you run rich due to a 255 without an afpr. The richness comes from an increase in pressure. More pressure= more flow when the injector opens. The stock FPR is not capable of returning the excess flow to the tank and maintaining the suggested fuel pressure. This causes an increase in the...

It's easy to check if its the fiav. Disconnect the throttle body lines and loop them. Let it idle for 10 minutes and see if it still smokes. Mine was leaking and I had the same symptoms.

Check the Tech articles here, I made an article detailing the install. I finally got most of my issues worked out in my car and am able to start driving it, so I might be posting up a little more to the MS article.

Lambda is the reference to Stoich. Stoich values are different for different kinds of fuel. Lambda is a ratio of the afr ratio to stoich. The advantage to using lambda is it always gives the relationship to stoich. But most people don't think in lambda values and its a lot easier to read 12:1...

Alright, I am trying to narrow down where the smoke could be coming from. Disconnected the IC pipe from the throttle body and looked down the pipe, no oil. So its not my turbo seals. Rebuilt head and block, don't think its smoking from there. Valve seals would do it on startup, and it runs a...

First time I have ever run a vehicle without a cat, should the exhaust gas be colorless? It has a slight grey hue to it, and I am not sure if this is a potential problem, running a little rich or what? Does the cat affect the color/consistency of the exhaust gas, and since there is no longer a...

I thought that would be a problem. Basically I am looking for a stock timing map that can be used for a pressure versus rpm VE table. Thanks for the info.

That means that map ranges from -8 psi to 40 psi. I think the math is off...

That's cool, can you explain the math behind that? I thought for sure temperature would be involved in there and it wouldn't be that simple.

How would you go about converting the load to a pressure signal?

In that internal timing map, what are the units for the graph showing RPM to Airflow? It ranges from .5 to 4.18. Does anyone know?

Parts I need to add to be completely inclusive:1)Soldering 2)IAT sensor 3)Using Easytherm to calibrate Temp Sens 4)Mounting MS 5)Tuning 6)Include base MSQ

Diagram for the harness. The only wire that needs to be run is for the intake air temperature sensor.

This document is intended to be a step by step guide to configuring a Megasquirt board, creating a wiring harness for the car, and getting MS to run in a DSM. This document could not be possible without the help of Jerry at diyautotune and Scott (dieselgeek). Thanks a lot for your help.Now...

Yea, guess its time to bust out the white paint...:rocks:

Ok, I just went and checked, I rolled it back to what is supposed to be tdc according to the cams. Pistons 1 and 4 are definitely at the top. So I know my timing is in order. Now the problem is there is no notch whatsoever anywhere near the 0 TDC mark. The only notch is a good 90 degrees away. I...

Ah, thats a good call, I will try that. The timing right now is showing 40-50 degrees, so something is off.

Does anyone have a good picture of the timing mark on the crank pulley? Mine is broken in one spot and appears to have two notches, I am not sure which one is the correct one for timing.Are there any marks on the front of the pulley that correspond with the notch?

I am using megasquirt, it has internal VB921 transistors to control the coils.After some searching it appears I could swap out a 90 coil pack to drive the gauge? Would this work? The 90's coil pack creates the rpm signal off of the actual coil, where as the 91-94 uses the ignitor to create...

I am no longer using the stock ignitor. Does the 90's coil pack depend on the ignitor? Or is a seperate part that generates the signal? Can I just use the 90's coil pack and run the tachometer signal to the 91 tach wire?

Where does the gauge get its signal for RPMS? Does it come from the ecu or is there another source? And what is normal operating temp?

Hey, I am installing an MS and want to know if the coolant sensor wire running to the ecu also powers the gauge in the cluster? I notice there are two sensors on the thermostat and wondering if the gauges have their own, or if that is for fan control? Does the ecu control the fan, or is that...

PM sent

This might be extremely ghetto, but it worked for me. I got a rubber washer that barely fit over the threads, out rtv on the threads, and torgqued it down. Doesn't leak anymore.

Yea, powdercoating costs money, I was originally going to polish it, but I got lazy :) I didn't really want to throw in a half polished manifold, so I think I will paint it.

Are there any negative side effects to painting an intake manifold such as heat soak or anything? I have some high temp caliper paint left over and was thinking I might paint the IM while I have it off.

So would there be any difference between these two. I think they would be the exact same in feel, so I am opting for the cheapest ones. ROFLOption1...

What's the max power a stock 420A has made? I was under the impression they couldn't touch 250 to the wheels without a rebuild. I agree with the "pizazz" factor of turboing your own car. It's always better when you can say I built this. But I don't think the original poster really cares about...

I don't post a bunch of negative remarks, I am post reasonable decisions. He obviously doesn't understand the task and can't handle it without paying someone to do it. That's not cheap, is it? How many stock gs-t or gs-x do you know of? A simple boost controller and they are putting out more...

There is no link....:confused:Reasons why I turboed my car: 1) Bought it that way :thumb: 2)After going through it fixing it, I could do a swap in probably a matter of 2 hours. 3)Its a 4g63, ecu and all parts are readily availableReasons he shouldn't turbo it 1)He is asking for the...

Nitrous is your answer, you want cheap and fast. Mine is originally a 4g63 to begin with, so I could just rebuild it with turbo internals and everything is good. You are talking about taking a 420A and turboing it, thats a whole different story and complication. You could do it for a grand, if...

Not worth it, unless you know what you are doing, should just keep that one the way it is, especially if you want a reliable car.

Cheap and turbo does not go together. You will spend quite a bit to get as fast as a normal turbo, so you might as well sell it and get a turbo model.

What is that blue color?
