My DIYPNP install! Options

[Syaoran]

I forgot your DIYPNP is for the 3SGTE, right?

Yes. Are you running yours on a 5sfe?

Yep, the distributors are different, I believe. 3S distributor is more like the one I have that I was gonna modify (various teeth instead of the 4 slanted teeth)

That would be awesome!

Haven't forgot about you. I need to find time to rummage through my storage shed to find it.

Thanks. There were really two small issues that were preventing me from getting the car running. One was that my injectors were not wired up by firing order for sequential injection. The other was that I was taking a cam signal form G1, when the basemap for MSPNP looks like its setup for G2. After switching to the G2 distributor cam pickup, the car fired right up!

I would have had this running a lot sooner, but everything got put on hold due to school, life, work, etc...

If anyone is interested, I can post up the 3sgte specific information needed to get the DIYPNP running on any 3s.

I, for one, am interested. Probably going to be the next thing I do to my 3S after I replace the head gasket.

thats AWESOME art!!
Definetly post up the info, if you have pics or anything, let me know, I can actually host them here on the site so that when we sticky it, the info will be there as long as the site is. lol

Definitely interested, was kinda waiting for you to figure it out first Art

Nice work!

Hahaha, really? Why am I the guinea pig?
You can order up your kit and start soldering. There is actually quite a bit of work to do before you get to the 3sgte specific portion.
I'll make a new how to thread in a few days or weeks. I want to make sure everything is finalized so that I don't have to make corrections later.

One thing I learned is that an EMS does not just solve all of your problems. If anything it creates brand new ones, but you do learn a lot. For example, just getting the car to free rev nicely and fall back to idle requires some know how. You would think that idle is purely related to your idle control valve, but actually your timing map plays a bigger role and there are some tricks you need to know. I finally got mine figured out.

Right now I'm trying to figure out how to get my injectors to cut off when I let off the throttle. Things like this you take for granted with your stock ecu.

One HUGELY helpful thing is AUTOTUNE. Its a feature of Tunerstudio (plan an extra 60 bucks in your budget, you're going to need this), that adjusts your VE map based on a target A/F ratio map that you provide. You just set it up and it fine tunes everything for you as you drive the car around. Beats sitting there with another person and trying to communicate what you want them to change. Its amazing that Haltech and a few other big name ecu's don't have this.

The timing map will probably also need to be dyno tuned. The one provided is just a base map, and far from perfect. In some areas the car had more power stock and other areas make my JS Safeguard light up like a tree.

But overall the car drives very smoothly and the ecu seems very reliable. Really surprising for something that started out as a bag of resistors on my desk.
