I have only used Karmann before so I don't knoow hotwire
Any ideas?
Thx,

Got my S-AFC in today - looking good so far!!
Now a question - do we use Diagram T-10a or T-10e I read T-10a but the manual I got with it - saying we use the Celcior - says T-10e??
Thx for your help and the diagrams man,

You use 10e I think in the old S-AFC I they refered to 10a but GURU did use 10e in his 99 GS400 see is post.

If you check that diagram w/ the SRT ECU wire diagram you notice it is exactly the same. bt you notice that they use a differrent RPM wire. I notice tis when I was tryin to find the ECU wiring for the GS 430. They use a differrent RMP wire on it also.
I got mine hooked up and the SRT worked finr and when I put the S-AFC II on It did read the correct RPM. I traced both wires from what I can tell SRT usees the signal going to the RPM guage and Apexi uses one from the ignition from one of the coils.
I see you have the SRT intake also have you dynoed it yet?? I'm working on making a by pass so that when I get my S-AFC tuned I can switch to the SRT ecu to see the difference so I don't burn up too much dyno time, well that's the plan.

Yeah, I have the SRT intake. I never dyno'd it after installing it - but I am confident that it didn't give anywhere near the increases that it is supposed to.
I am planning on removing the ECU that came with it and tuning the car with the S-AFC as soon as I get the headers installed.
I should pretty much have every mod available for the car except for FI. With it tuned on the S-AFC II I am hoping to have somewhere a lot closer to 300hp at the wheels - but I know that is reaching. With the headers and properly tuned, as well as the exhaust I am hoping to make up some of the 60hp loss at the crank.
So you think 10e then?

How do you know the arrow should be pointing straight up? I think mine's pointing at a 45 degree angle.
Thanks for any help!

Hmmm... RTFM Paul...I'm reading something called AFC2Wiring.pdf I'd saved locally ages ago and it shows HW13 for the sensortype for a 1UZ-FE in a '97-'00 Celsior which I think is the same as the GS400 engine??
Dx3 - I assume you have this doc and the operating manual? I have all of the SAFC and SAFC2 docs in PDF form locally.

He reads further... the "safc_us_update.pdf" document which does talk about "American Market Vehicles" and says the diagram for the GS400 is "World 10-a" (not 10-e) and the sensor type is HW13.
When it says have the throttle 'closed' or 'open' during initial setup, which way is which? (Excuse the dumb question!) I assume closed means foot OFF the pedal and open means foot to the floor???

Now you are confusing me even more!!! I asked the same question a few posts up - the manual says T-10e but the US update says T-10a
About the arrow up - the 45 degrees is up so that is ok.
The 13 confuses me again - Gil said that it is set at 13 but yours is at 1
Very confused!!

Jonny thanks for the heads up on the arrow. Do you have these pdf's I mentioned? If you need 'em I can e-mail them to you if you pm me an e-mail address.
As far as the HW setting, the docs say 13 so I guess that's what I'm gonna set mine to if I don't hear otherwise in the next day or so on here!! It's weird, I've never had a problem with the way it's been and I've seen it do it's A/F correction from 4000rpm's up so WTF?

Do you have a copy of SRT's HIFI GS400 intake instructions? I did a lot of research trying to find the correct ecu diagra for my 430 noone seemed to have done it or they never replied.
It shows the sensor type and # as " HW13" for the 1UZ-FE ( GS400) and "HW25" for the 3UZ-FE engine (GS/SC430)
The sensor number confused me too for along time. I still don't know how they arrive at the sensor #. I believe it has something to with matching the current signal coming in vs. out on the MAF.

Yeah man, I grabbed them from the site already. Thank you though.
As for the 13 - I am also!!
As soon as these headers come in I will let you know!!
