Hi everyone sorry its been awile since Ive been on been dealing with these California wild fires and waiting on a chip. So, I ordered a new chip, but I seem to be having the same problem. The car seems to run fine at part throttle but as soon as I get in it it knocks as you can see from the log. Here is the new log with the new chip.

3rd gear isn't showing. Is this chip burned for the exact combo you're running?

As far as the chip it is sorta  burned for the set up, I will explain. It is not the specific chip for the set up. The chip was burned for stock fuel pump, stock injectors, stock lock up tranny, and torque. Everything is true except for the transmission. The transmission is a non lock up stage 2 tranny, with a non lock up 2800 stall torque.

So I have fixed the speedometer and took two more logs. The first log was me taking off out my driveway. The second log is on the freeway. At part throttle it seems to pick up great and pull and go. However, as soon as I stomp down it knocks, runs thru my knock sensor lights like a champ so I just lift. It goes away and once again able to pull hard at part throttle.

The mph is not working I think do to the cable every since I went to the stage 2 tranny it stopped working thinking. Right now I have a tt chip 5.7 set for stock boost, injectors, and fuel pump. The only thing different is the transmission deal.

I'm getting some weird knock with a gn I just picked up. Short story is I picked up this gn and after going thru it and replacing what leaked or didn't work I pretty much brought the car back to stock engine wise. Once everything seemed fine I started to check out all the parameters and everything checked out on the powerlogger. Right now what I have is a stock turbo, stock fuel pump no hot wire kit, stock injectors, lt-1 maf with translator. I didn't mention the chip because I had a chip with the same engine parameters as what I have the only thing different is that the chip was burned for a lock up transmission and torque and I have a extreme automatics stage 2 non lock up with a 2800 stall non lock up torque attached to the engine because the stock one gave out so I put this one I had for my other gn in it. Now to the knock issue. The car idles fine and even drives fine at low speeds and gears. Everything parameter wise is also fine when cruising around town. However when you decide to get in it it will pick up and boost strong for a little bit then when it seems like it should either swithch gears or just keep pulling all of a sudden it starts to knock retard and act like it won't pull or shift anymore. I've included a log hopefully its not to long.

Figured I shave a few pounds and still keep the factory look so first thing I did was take the floor mats out. I have a 2bar map sensor right now. The fuel gauge is mechanical and the maf is new as of a few weeks ago. With the car on engine off pedal to the ground tps reads 4.2 ish 4.3 range the last time I checked. I never really checked the throttle cable or the accelerator pedal. I will do this as there is still a little day light out here and go back and check the tps again as well.

Hi and thanks for looking at the log and bringing it over. Yes I do have a fuel pressure gauge. When I looked at the fuel it was about 2lbs low so I adjusted it up. After doing this it still showed knock at around 8 lbs. The fuel reading gets up to about 52 lbs under wot. However it won’t go past this and that’s when the knocking starts. I have a walbero pump and yes it’s hot wired. In the log when the knocking was the worst I should have been in wot. The maf is a stock ACDelco unit brand new as of a few weeks ago.

I’m in California I did a run earlier and the fuel pressure was down a little bit. I turned it up, but it’s still doin the same thing. I’m still working on trying to get the logs posted, I have a cousin who is very computer literate and will be working on this issue tomorrow.

The fuel pump, I will hook up the fuel gauge and take it for a run and find out. I just put 80lb injectors in. The boost is at 8lbs. So. I should be around 51lbs at wide open throttle right? Is there anything else I should look out for. In the frame with the knock at wot the tps was at 2.74 should I be worried about that.

The o2’s were .768. At the time the knock count was 6 and knock retard was 4.8. The maf read 178.3 at 7.9 boost. My tps was at 2.74 and the mph was 50. The knock starts and won’t go away until I lift.
