Installation / Re: Busted my sheild help.
« Last post by Chummins on August 30, 2018, 07:12:13 PM »
thanks for the response, I basically used the numbers on the header plug .  so it ended up like this on the  header it self.   
pin 1,Bat + . pin 9 ,Gnd. Pin 8, can L . Pin 16 Can H.  pin 4 and 5 are VR sensor and were not mixed up.

I noticed the VR IC got realy hot , but I did power it up 3or4 times for a few seconds , the first being to longest at about 1min.  I didn't check any of the resistors or diodes to see if there done , nothing looks burnt or damage , just no response/action to the turbo.  and its stuck wide open @ 0 boost  :o

PM me if youd like also , ill check more often tomorrow.
What would be the lead time for a new shield?(trying to avoid that tho) 
Thanks
Cheers

Hmm I'll reply a bit later just letting you know I'm here. Just really busy.

What pins went to what when you first wired it ?

Installation / Busted my sheild help.

So was waiting for so long to use this controller, finally got my engine in the truck, and I'm pretty sure I fryed my brand new sheild.
I Used the pin numbers stamped on the header plug and not the header itself.  So basically it was wired reversed and I was feeding 12v and ground to the can bus  :(....   so I repined the plug correctly and re test. The ardunio powers up but yeah nothing works still as expected .  I'm assuming i fried the Shield .the controller seems ok. I can read and write no problem.  is there any self test i can do? Any way of checking the ic's? I know the VR ic (ic2) got hot .  At this point im just hopping the actuator on the turbo is ok.  let me know what i can do or test to see what I can replace or do I have a expensive paper weight.   :'(
Thanks

would putting the mating surfaces on a flat surface and sand flush not work with some copper RTV?  just wondering.

Yep, that'll be fine.. I was thinking of getting something similar so I can read the ABS ring on the rearend for vehicle speed.

Wow... That hadn't even occurred to me... I ordered this guy for the VR conditioning - https://wtmtronics.com/product/mini-max-a2-signal-conditioner-vr/. It is based on a MAX9926, same as a MAX9924 but dual channel, so I have a spare channel if it ever stops working.

yes, VR sensors easily make 100V AC which will fry it instantly

Pin8 in freqmeasure measures pwm from a 0-5v square wave.

Don't send the vr sensor directly to that pin. You'll need max9924

yes, I think pin 8 is used for freqmeasure...

Progress is always slow on projects!
