Sorry guys... the Apexi S-AFC DOES NOT work... *sigh*

Well after attempting to re-install the Apexi S-AFC.... and hooking up the potentiometer type TPS from the 240SX..... the Apexi S-AFC is a failure..

 

as I read on a BMW website, I needed to set the sensor voltage type to 01 out of 15 settings...

 

anyway... no matter what settings, or sensor types or voltage types or fuel increase it ran very rough and would intake backfire and detonate (sounded like popcorn)..

 

it would idle fine, but over 1,000 RPM it all went to hell...

 

 

Here's my conclusion....

 

the Apexi S-AFC will NOT work with the stock 280Z L28 electronics, nor the 280ZX stock electronics...

 

there has been results with a 300ZX ECU and MAF.... but our flap type AFM will not work.

 

I can however, convert the AFM with a BMW MAF (no flap and hotwire type sensor).. or a Z31 MAF.. but it would cost some more money...

 

Anyway... it was cool to see the throttle position, and O2 sensor readings, and RPM all on the same display in bright blue.. but ehh.. boring

 

i'm going MEGASQUIRT!!!

Warning ***Shameless plug***

 

Do you have a Megasquirt yet? If not, I have the MS fully assembled and tested, Relay Board assembled, and Stimulator Board assembled and tested. I also bought the precut aluminum box for the MS and the Relay board. I have not gone further than full assembly and testing (and playing). No cables are made. I changed directions (using a Holley Commander 950 with Stealth Ram) and would like to sell this.

I personally assembled and tested it. I have an electronics bench in my home office with full ESD protection and professional tools (PACE soldering iron, digital scope, etc). I have performed electronics assembly work on flight hardware spacecraft and have passed the soldering requirements and ESD training.

I told you it was shameless, sorry.

It won't hurt my feelings if you can get one already assembled. If he will give you a good price on that setup go ahead. Sorry to hear the experiment ended up a bust, but most of the fun is trying, and I'm sure you learned a few things from it.

I am not sure if you were asking what I wanted for my setup. I am not in this to sell assembled board for profit, instead, I was going to use it on my car. Just changed directions.

I am not looking for any money for assembly, but would hope to get close to what I paid for the parts. I don't know what the price is from Glen's Garage. Make an offer.
