emanage blue on rev 1 5sfe

[Guest]

Hi All,

I have a greddy emanage blue which i want to use with my 5sfe

problem is, that it is a rev 1... and has no variable throttle position sensor. (either on or off only)

Is there any way arround this, as the emanage's maps are rpm vs tp

also does anyone have any idea about ign wiring... is it the same deal as the MSD-BTM (wire it between coil ground and igniter) or is it different?

any ideas (besides get a diff piggyback, or get a megasquirt, or whatever) would be helpful...

are you serious that your TPS is just an idle switch?

I've not seen a toyota TPS from the mid-80's onwards that is only an idle switch... how many wires does it have?

Its slightly more than an idle switch

it has 3 wires... common, idle, and wide open.

in that case grab a greddy or other map sensor and change the load reference in the emanage to the map sensor.

For the ignition you just have to intercept the IGt trigger from the ECU to the ignitor.

So would i wire the TPS wire to the power out on the other map sensor?

no, you plug the map sensor into the yellow option port on the emanage. I'll have to go and confirm in some of my old emange blue maps that you can select the map sensor as a load reference in the airflow map, from memory only the later firmware/software allowed this. In the original software you could select the load reference in the additional injection, ignition and sub-injector maps only.

Well, ive got another toyota map sensor im going to use for a turbo project, i will give that a crack for the time being.

AFAIK, exact same setup on E series engines.

Ok, here is the plan.

First, here are the wiring diagrams for both TPS's

REV 1

REV 2

Plan is, test both to see what values i get at idle, wot and somewhere in between. if the rev 2 tps has a WOT switch like i suspect (VC) then i will wire it as follows

REV 1 REV 2

E1 E2

IDL IDL

PSW VC

eMg VTA

[CHA54]

VC is a +5V sensor feed from the ECU, it's used to power things like the TPS and MAP sensor.

Poop.... guess im going to need to go make some kind of WOT switching circuit.

[Guest]

ok... next thought

see below diagram.

at WOT VTA should provide enough power to make the rev 1 ecu think its WOT... so it might be OK.

ninja edit: i just hope the ecu's 'trigger' voltage is not less than 4v

ninja edit 2: and that i can pull a 5v output from somewhere

after much tooling around, and having the car decide to idle @5500rpm for a bit, the new TB/TPS is installed and seems to be working.

I haven't tried to read the TPS with the emanage as yet... will do that soon and report back

[DJKOR]

Well as long as nothing is blowing up... all seems pretty good.
