That makes sense. What happens with too big of a waste gate then? Doss the boost fluctuate because it bleeds off too much or something?

Well I might just have to go with the extra muffler then. You brought up something else I never even thought of. I didn't know you had to size waste gates for the turbo application. Yet more things I need to think about...

Yeah, I have the other valve covers as well. I thought I remember reading somewhere that the ge manifold flows better. But, as IJ and supracentral say, don't trust someone who says they "read it somewhere" or "heard it from someone". I just wanted to know if there was any conclusive flow testing...

Hey I have a complete GTE and GE engine and I'm building the GTE up. Is there a benefit to running a GE intake manifold on a GTE motor? I will be going COP so I won't have coils in the way. Plus I will be able to run the better looking GE valve covers.:icon_bigg

The reason why megasquirt can't run a unipolar motor is because unipolar means the coils inside the motor itself are powered with only one polarity. That's why the two center red and black wires are connected to 12v on the stock ecu. To make the stepper motor "step" through its range of motion...

Well, I decided to be different and fabricate an optical trigger for the engine. This should prevent a lot of noise from getting mixed up with the lines and also get rid of the sync errors I get. I'm pretty much taking this drawing here and modifying it to work with the CPS. Shouldn't be too...

Damn. I guess I need to get a welder. Someone could stand to make a few bucks if they made a downpipe that was built with an external wastegate in mind. I'd sure buy that! I guess it would be a bit more difficult with all the external wastegate positions and such though. Maybe if you made the...

I did a search on this forum and SF and I haven't found an answer. Is there an exhaust system that takes the external wastegate and reroutes it back into the exhaust system, or is that a custom fabricated sort of deal? I would like to convert my 7m to run a t4 v-band turbo, but the only thing...

I actually tried that as well. I have been reading on the ms forums and apparently, the on board vr conditioner sucks. I don't want to blame the equipment though. I must be doing something wrong if others are succeeding where I am failing. There is a different vr conditioner board that I could...

Indigo, thanks for the link. I just tried that but it still doesn't read below 480 rpms. This is frustrating. I might just go with the optically triggered solution. It's weird that this doesn't work like it should. In tuner studio, it has a trigger diagnostic program and it reads up until the...

Well, I've run into a snag. Maybe one of you guys can help. I'm running the stock cps with one tooth ground off it. From many of the other build threads where megasquirt has been used, this is supposedly the way to do it. Anyway, I decide to bench test the whole assembly using a drill to spin...

Hey everyone, this is posted for my younger brother because he got himself in too deep and I'm trying to help him out as much as I can since he has little experience with engines and cars in general. Anyway, he bought a 1997 Lexus SC300 with the 2jzgte swap. You can see the swap here...

You got a point there. That would be pretty cool! The other issue I am running into is the double glazing on the windshield. It shows double images for the display. I'll take a picture of it today and post it. Oh, is there an easier way to swap injectors? The TSRM shows having to remove damn...

Hey thanks. I checked the HUD feature with my phone. It needs a larger screen to really work. I'm buying a nexus 7 here in a week or two and am going to try and fabricate a mount where the stereo would normally go. I might also be able to set it on the dash for the HUD feature to work as well. I...

Hey thanks! :icon_razz I will work on that tonight when I get done with work. On my lunch break I finished building the cable that goes from the megasquirt computer to the relay box. I tested it and it work as advertised. 37 wires had to be cut to the same length, stripped, with heat shrink...

Eventually I plan to. I'm debating right now on ditching the weird double din setup in the car and running a Nexus 7 in there. :naughty: I could run an external hard drive full of music on there and also use the bluetooth as a digital dash. I would love to swap the gauge cluster out for an LCD...

The power is supplied via megasquirt. Megasquirt can drive a bipolar stepper motor IAC, but not a unipolar IAC. The way the stock ECU drove it was with by grounding each coil like you said. That is the unipolar way of driving it. That's why it needed the 12v power. Megasquirt supplies the power...

You can run the stock ISCV. You really don't have to rewire it either. It works perfectly. You don't connect the two middle wires to anything. Just run the 4 outside ones. It works. Look at post 4 in my thread...

Here’s another update for you guys. I finally got my Bluetooth link working for megasquirt. I didn’t see the point in buying a $80 bluetooth adapter, so I found one on ebay for $7 with the wire harness and backplane. As a tip for everyone else, don’t buy just the Bluetooth module. It runs on...
