1st Gen Haltech ECU Discussion

Our density altitude has been like 300-600' lately. Plus ambient temps around 35. That's the weather for making power

 

The high today was 68° *sips tea*

 

Yeah, in AZ... Deal breaker, although the DA at Firebird in Chandler was only 985ft today, that's exceptional for PHX area, it's usually just awful.

Was a pleasant 45 and sunny today here

 

It's 73 in my house rn and I'm wearing a jacket lol. 45? F that

 

I don't even heat my house that high in the winter, if it's that hot inside in the summer I'm turning on AC. I don't miss the heat, 45 is hot here in winter too. It's been a really warm winter so far.

 

Yea, it has here too actually. We'll see if January has anything to say about it

 

Just throwing this out there, I am probably in the market for another Haltech for a different vehicle so if anyone wanted to ditch their 750 and upgrade I would be interested in a deal

 

Damn, think the spare 750 around my shop just sold. @2RZNoShi1, that guy bought it right?

 

Yeah, he already bought the boomslang and everything. Just waiting for me to swap in the 1500

 

Probably more than you are looking for but my buddy has a new Nexus S3 that he has changed his mind on; a couple hundred savings off from new.

 

I was considering the S2 actually. What's he not like about it?

 

He planned to swap out his 2500, but decided against it after realizing the changes he would need to make to fit the S3.

 

...like dimensionally or...?

 

Yep, dimensionally.

As far as knock ears go, something like this could work if I spice the knock wires into the inputs?

We used one as simple as a pair of nice headphones and a single bosch wideband knock sensor wired to this little headphone preamp... works pretty decent

Separated those conjoined trigger grounds.


Pro tip from @Speedytech7 to just unbolt the harness and pull it into the engine bay.
So far seems to have solved my random desync issues, but for some reason lives at 7% of valid home travel now.

 

Had a good time wiring in trans control to the A340 on @Digiratus' tacoma with @2RZNoShi1. While doing the install I made a handful of notes about things that could be streamlined and simplified and @2RZNoShi1 noted some interesting things about setting up the tune to work properly with 4LO as well. For those of you with A340s that have a temperature sender (rather than a temp switch) I also mapped the sensor resistance for temperatures and converted the data for use on any AVI or SPI that has a 1k ohm pullup to 5v, if you are going to put it on an SPI with a 10k ohm pullup then you'll need to convert the values.

 

There were definitely some good lessons learned.

 

Did you take the factory ECU for some skeet shooting practice yet?
