Has anyone used megasquirt and removed 2 teeth from the factory CPS (24-2) to get a steady RPM signal? I'm stuck getting an rpm signal that bounces and hits 0.. Can't figure out what the problem is at this point!
7MGTE Megasquirt Trigger, anyone done a 12-1 modded CPS

Is your car running or no? If not, see if this link helps. I have never used Megasquirt. You should E-Mail their technical support and see what they say.

I did it! My car runs great.
Try closing the gap between the sensor and the wheel, that fixed it for me! If you have any other questions just LMK, I just successfully finished my megasquirt project!

Get a hold of gennro on the forums. He had a buddy do this, and he, himself is a very smart guy when it comes to that ecu.
Glad to hear you've got it running . I'm running MS2 also(with a crank trigger). Gennro helped me set mine up too. So if you have any snags , let's chat about it . Good luck
I'm getting an rpm signal, it just drops to 0 even while spinning consistently by hand.. the composite logger is showing sync loss too.. I've got something to try today, if it doesn't work I'll post the issues
I just let it touch the wheel and backed it off a hair, never measured. where do you have your VR sensor grounded?
Can I ask why you all are using MS when there is a DIYPNP for the N52 or N76? I only ask because I am rebuilding a 7mgte that is going my my 85 mx72 (cressida wagon) so I will most likely go DIYPNP for ease of standalone along with the ability to tune later down the road.
Because the DIYPNP is not actually PNP at all. The harenss physically will plug in, but there are many modifications to be done to get it to even fire up.
With MS you can build the system to your own specification using any ignition, fuel, sensors, setup that your heart desires

Sweet very good to know, but would you say that with MS the needed modifications/wiring would be less hassle then "DIYPNP"?
Excuse the question, not looking to sidetrack the thread and I am new to 7mgte so I am still searching. I have experience with MS2 on my miata, and MS1 on my brothers NA miata, but going with a engine into a different chassis makes me a bit nervous so MS/DIYPNP seem optimal.
Well if you have experience with MS2 then you should know that the ECU is running the Engine , not the chassis . So it doesn't matter if you put it In a Ford truck . It'll still run the motor. Don't think of it as a more confusing process because of the chassis change.
Yah just freaked out thinking about all the sensors/ reading all the harness work to convert, but I found this guy running MS2 on his 7mgte in an older chassis. IDK what I was thinking lol, probably easier to build it along with building a harness as well.

Sorry to be posting random crap in here. Thanks for all the info.

Well, my MS2 setup on a 7MGTE is in a 1977 Celica Chassis. From starting to assemble the computer, to on the drag strip running 11's in 2.5 months!
I'm running VEMS on my 7mgte using the altered stock CPS method, and I'm selling the motor to a friend, but keeping the VEMS box.
He is buying a VEMS box, and needs to know if he needs a Hall Effect setup or a VR setup.
Shamefully, it's been so long since I did that that I don't remember. Can someone enlighten me? Does the 7m's stock CPS use a hall effect sensor or a VR sensor?
Thanks
