Burst knock retard does not show up as actual knock retard. You won't get more than about 40° advance into a distributor that has the base timing...

Great, thanks for the support! It sounds like you think a Pi would be the easier than Arduino. I have seen that the Arduino also has an FTDI addon...

Easy enough to just disable it before a smog test. :P Even easier if it's a patch that allows for an external trigger pin. ...isn't that just...

yes that's a wicked project, i'd be glad to help, 100% on board. i have many projects that have completed that parallel this one we can reuse code...

Knock sensors work perfectly. New Delco sensors that went on the engine 6 months ago. I know they work because I occasionally see 1-2° of retard on...

Since you're from Californicate (I was too) I don't think you'll be able to run HLC anyway. FWIR you won't pass smog with it enabled, that's why GM...

forgot to quote Fast, he needs the new knock sensor/ module

LS1's started at 0.060" and then GM released a service bulletin to drop the gap to 0.040" because of misfire complaints once the engines got some...

{delete, replied to wrong post}

I think you need a new knock sensor.

Not to get too far off topic, but USB based scopes are crazy inexpensive now. You might want to consider buying one, as it'll pay off huge when...

Scott, The VOM meter shows 12V high and 0V low but still sets the code. Wish I had access to an o-scope. For the crank sensor I just took a...

Great to see someone else running a 411 PCM on an old school motor. I've got a 411 running a '70 Pontiac 455 backed with a 4L80E as well. I took a...

Give me your tune. Not even joking. My stock LT1 on 91 (E10, winter formulated) knocks at only 38 degrees of timing under load. If you’re saying...

Actually with lead in the avgas they have to vary the power setting every 30 minutes or so to keep from fouling the plugs. Forgetting the P38, I...

So I am curious how are you guys ( Steveo and Kur4o) picking apart and writing patches for these ecu's. I am curious to look deeper at the Highway...

i am also new to LS droid , im having a problem with my first attempt to even read the ecm it starts the stops very soon and only displays a "?". ...

Wow, awesome price. Just ordered some to try.

with the '411 why not just run CnP and be done with it?

I looked up the exact seller I purchased from over 2 years ago. He does not sell the 5 pack any more but he offers a 10. Not sure if its the same...

I got my "fake SST" chips direct from China Sept 2017. They work fine with Moates Burn2. The only time I ever had a problem was when i plugged the...

Untuned individual trims for lt1 is number reason for crap running engine at light load. At idle they are relative easy to dial but off idle is...

I've been using Winbond W27C512 chips for a while now, most of the fake SST 27sf512 chips on ebay are the winbond chips re-labeled. The big problem...

The 27SF512 has variants, namely the speed 70-C3 vs 90-C3. The replica (MTP) chips with 90-C3 speed usually work with the Burn 2. The replica (MTP)...
