I would think you need tach wire too, but I assume this could be derived from the injector firing.

 

RE: Injector PW scaling for the fitment of bigger injectors...

I'm on MLR at the mo, a russian mate of a member on there is checking out the forums for any info

EDIT: No joy

 

For those who are curious, the units are on their way to those of us who decided to order them.

acamus, can you recommend any good (low-budget) choices for a PIC programmer that doesn't require a physical serial port? I don't need a burner (I already have an old Willem parallel programmer), just something that'll do ICSP, and preferably work with some Linux software (pikdev, piklab, picprog, etc).

Pickit2 clones on eBay look like the best deal right now (and pikdev looks like it supports it, with some partial support in piklab); this looks like the most bare-bones version available. I'd really love to find something off-the-shelf that behaves like a JDM-style programmer, but uses an FTDI chip instead so you don't have to deal with the power problems, because just about every PIC programming package you'd ever want to use supports the JDM hardware.

I'd also come across this Cytron device, which appears to sell almost as cheaply as the JDM programmers, but chip support looks pretty weak. It's apparently compatible with Pickit2 software?

 

Not really, if I would need one I would just build one on prototyping board.

 

I should have guessed that you'd say that.

I'm lazy right now, I have enough parts strewn over my desk (my wife has me working on a couple of electronics projects) that $13 on eBay looks pretty good to me at the moment.

I suspect the injector scaling will be really easy to find; I have both an Evo and WRX version coming to me, so a quick comparison of the two ROMs should make that jump right out.

 

I'm insterested but the metric bugs me. LOL. I'm not use to it.

Logic, when are you going to get it? Can you take a picture of it before the install?

I'd like to see a "How to" on this if possible.

 

According to the tracking info, mine is currently sitting in an international port in Moscow.

I'll be happy to take pictures of it and document the install once it arrives, although it really doesn't look that complicated to install.

 

IT looks easy but seeing pics would make it easier. Documentation would help.

Thanks!

 

Mine is in my mail box today, I will be doing the install as soon as I get home and I'll try and take pictures and do a write-up for everyone

 

Dammit, you got yours before me. Hopefully that means I'll have a package waiting when I get home, or tomorrow at worst.

 

Only think that I can not figure out with hooking this thing up is which wire exactly you connect the fuel level sensor to. It is separate from the ECU wiring I take it though?

 

Here's what I received when I opened my package. It included the 2 wires for the temperature sensors, wiring harness ( I labeled mine already to make things much easier when I go to install), and the manual that I can't read because it's entirely in Russian (was expecting that), and of course the unit itself.

 

I installed it today and I looked through all the diagrams I could find, I can not find the location of the wire for the fuel level sensor. Could anyone tell me where this is?

 

acamus mentioned earlier in the thread that pin 51 of connector C-02 on the back of the combination meter (gauge cluster) should be what you're looking for; according to the FSM, it's a blue single-row 21-pin plug (the plug should have two prongs on the right side, and three on the left, with a key in the middle; pin 51 is the outside pin on the three-prong side). It's also pin 74 on the ECU, if that's easier to get to.

Sidebar:

Apparently I really screwed this up when I wrote the pinouts for the VIII and IX up on the wiki. I have pin 46 listed as the gauge, and 74 listed as the low-fuel indicator, but that's obviously not right looking over the FSM circuit diagrams; I don't know what I was smoking at the time.

If I'm reading the FSM correctly, pin 46 varies current based on a 6.5 (full) to 78.8 (empty) resistance indicating fuel level on the passenger side of the tank, and pin 74 sees a combination of the resistance from the passenger side and a 6.5-41.2 ohm resistance from the level sender integrated into the fuel sending unit. Does that look right to anyone else?

(acamus, this is veering waaaaaay off-topic, but have you ever looked at the code relating to the fuel pump relay (pin 39 on the USDM cars)? I'm curious what conditions cause the ECU to toggle that relay.)

 

No, I have not been in that code area yet.
