Fatman.. i was told on another thread that auto tps will not fit my TB and i would need an auto TB. both auto and manual TB have the same part number:S

i have an auto tps coming over and it looks i cant use it lol. how did you change to the auto tps?

so when installing this, we dont need ecu? just plug it right in? does it have the base map?
no base map. but i think Fatman is going to provide us with a basemap to start the car! then you need to map it according to your setup/needs

I love this thread, I've been thinking of running megasquirt in my ep91 for a while. I have a couple questions, my car came n/a and I am about to swap out the 4efe for a 5efe on boost. My 4efe has the DIS, what exactly will I need in order to run this setup?

Well basically all I want to know is what will I need to run my DIS system. It has 2 coil packs by the way.

this can be run with the megasquirt as well but the setup is different.
the coilpack system runs from a 36-2 sensor wheel on the crank as the 4efte runs with a 24+2 sensor wheel in the distributor...

am i right when thinking that MS can work with High and Low impedence injectors? so makes it much easy to source some bigger onse?:)

Progressing :) Car will hopefully be complete and on its wheels later this week. Got hung up on a stubborn driveshaft seizing in one of my hubs, took a 3 ton press to get it out :confused:

Once it's up and running it will be final mods on the megasquirt and then road tune time and I can make sure all my wiring and other documentation is accurate. Later in the month it's booked in for a few hours on the dyno with a very knowledgeable tuner to extract the most out of the timing curve (something I'm not yet expert enough to do) and will have a power figure too :)

great.. good luck! sent you a PM with a part number for the auto TPS so maybe you can add it to the documentation, did you receive it?

also i was told auto TPS will not fit the manual TB.. and the Toyota EPC has the same part numbers for the auto and manual TB.. do you know anything about this? i have two auto TPS coming over and can check if it fits a manual TB but just wanted to know if you knew about this and found a way around?

thanks

I did and I will definitely be adding it to the documentation, cheers :)

I've got a manual GT, auto GT, manual glanza, auto glanza and auto 5e-fhe throttle body here along with a variety of linear TPS sensors from a few different toyotas, I'll be posting up some of the differences and what works and what doesn't :)

ok perfect, thank you very much. I will hopefully have a megasquirt project post soon.
