Gregor, did you get it working?

 

I haven't had s chance to test it yet. I've been getting long hours at work lately, but I'm off tomorrow. I'll stay up late and test tonight and post results.

I'm also adding sequential injection at the same time, hopefully I got that right.

 

Well, the fans are no longer constantly on. But now the car won't start, I need to do some more research on sequential injection.

 

lol. :P

 

Hmm...maybe I'll just deal with my fan problem for now. I also have sequential injection and it seems to be working. I used these instructions if that helps.

 

Thanks for the link, that was one of my several bookmarks. I just came back from a test drive. The fans no only come on when the right conditions are met(Thanks Braineack).

Now, I need to figure out why it won't idle after I park it and start it up warm.

 

Did you get the firmware updated?
It did help my idle to update it. All the buttons are in different places but there placement make more sense so it only takes a while to get used to.

 

I will give that a shot when I get back home. I thought it may be a heat soak issue with the IAT sensor. I will get more info as I start to drive the car again. It will be down for a short while since I just picked up a 6 speed tranny.

 

I wanted to update my fan issue for anyone searching. Not that I 100% figured it out but it is the ac system. I basically removed the ac relay wire that turns the fan on when ac is on.
With my 1990 that's the black with green strip wire at relay by drivers head light. I used a little flat screw driver to remove the pin. So once I figure out Ac issue goes right back.
Once ac was not telling fan to turn on ms diypnp does it no problem.

Now to find out wtf is going on with ac but it's winter I have time. Lol

 

a/c relay activates the a/c compressor, a/c fan, and main cooling fan relay.

 

Thanks your correct.
My compressor clutch is not kicking on while I was trying to figure this out. It also does and did not turn on via button in dash. Might be broken.

Second fan was never reinstalled after mishimoto radiator.

I am going to try a new ac relay but I believe by removing only black green wire from ac relay I removed the wire that the relay uses to tell the fan relay to kick on. In my mind even if I never reconnect it ms will turn fan on at 185 whether ac is on or not. Might loss some ac cooling with less constant air flow over condensor?

 

Before I start messing with anything on my car I wanted to post a shot of the soldering on my DIYPNP2 on my 95 to see if it might be a hardware issue.




Brain, and anyone else who knows what to look for, do you see anything obviously wrong? I finally have a turbo kit to install and I want to sort this out first!

 

I can take some photos from another angle if that would help...I'd like to resolve this fan thing and it doesn't seem to be a software issue.
