Guys,

Last night i accidentally played around with my turbo timer settings

I think i went into the A/F and 02 settings. This happen in the morning

Later that night i was driving home and noticed after 3000 rpm the engine wouldn’t respond and boost wouldn’t kick, after half a second later it responds and the car jumps also i get a pop noise from my exhaust....

im not a expert but i think i stuffed it up by playing around with the settings or

because of the mods ive been doing i need a new flue pump or my air filter is clogged

Does anyone here know how to return a apexi turbo timer to default settings?

And up to how much kws does a stock fuel pump support? (r33 gts-t s11)

Any feed back would be greatly appreciated

Thanks babylon

It probably isn't the turbo timer (Apexi Auto Timer?) The (predicted) A/F and 02 values are just metered and you can't change anything related to the actual settings of the car.

But looks like your ECU 'limp home' mode has been activated.. it sets rev limit at around 2500rpm and runs rich to protect the engine against damage. Check your ECU diagnostics and clean your AFM.

Stock GTST pump is good for around 200kw at the wheels. I didn't have any issues at that power with my standard fuel pump, but I decided to upgrade it to a Bosch 044 anyway, just to err on the safe side of caution.

Thanks for the reply

sorry to be a pest but how the hell do i check my "ECU diagnostics"?

First step is to find the ECU and start your car. Look at the side of the ECU and see if there is a LED that is red. That will indicate the car is in limp mode.

If so then do the diagnostics.. which you should be able to search for!

Found my ECU its under the passengers seat , started my car looked under and didn’t see any red LED, only saw cables.

I changed my air filter back to the stock one unplugged my AFM plug then plugged it back in Rebooted my ECU by taking the negative off my battery drained the juice out of the car ...put it back on then went to drive the car same thing after 2500rpm the car jumps and does rev higher!

Today im going to get a new Fuel Filter and some electrical Contact Cleaner.. (hopefully works)

Im having a difficulty looking for forums or tutorials on ECU diagnostics

    • Oops... I meant to include the connector  view... BR/W - power from fuse L/W - motor negative to fan control amp (and off to HVAC pin19) OR/B - PWM signal (from HVAC pin20) B --  ground  
    • Yep, if you are applying filler it sounds like there is something wrong with the body lol. Safe to assume there is going to be a lot of sanding going on if your still applying fillers.  Picture a perfect bare metal panel, smooth as glass. You lay down your primer, it's perfect. (why are you going to sand it?) You lay down the colour and clear, it's perfect. No sanding at all took place and you've got a perfectly finished panel.  You won't be chasing your tail, sounds like you were prepping to start laying filler. If your happy with the body after the sanding, there is some bare metal exposed and some areas with primer, no issues at all, start laying the filler. You are safe to lay filler on bare metal or primer (of course check your technical data sheet as usual for what your filler is happy to adhere to).  This isn't a 100% correct statement. There is primer that is happy to adhere to smooth bare metal. There are fillers that are happy to adhere to smooth bare metal. Just make sure you're using the right materials for the job.  Typically if you are using filler, you would go primer, colour and clear. I've never seen any instances before where someone has laid colour over body filler (maybe this happens, but I haven't seen it before). So your plan sounds pretty normal to me. 
    • I don't think there's any way someone is push starting this car.. I honestly can barely move it, and moving it and steering it is just flat out not possible. I'm sure it is, but needs a bigger man than me. I have a refurbished starter now. The starter man was quite clear and consise showing me how nothing inside a starter really should contribute to slow cranking, and turned out that for the most part... my starter was entirely fine. Still, some of the wear items were replaced and luckily it didn't show any signs of getting too hot, being unfit for use, etc. Which is 'good'. I also noticed the starter definitely sounded different, which is a bit odd considering nothing should have really changed there.... Removed and refit, and we'll pretend one of the manifold bolts didn't fully tighten up and is only "pretty" tight. GM only wants 18ft/lb anyway. I also found a way to properly get my analog wideband reading very slightly leaner than the serial wideband. There's Greg related reasons for this. The serial output is the absolute source of truth, but it is a total asshole to actually stay connected and needs a laptop. The analog input does not, and works with standalone datalogging. Previously the analog input read slightly richer, but if I am aiming at 12.7 I do not want one of the widebands to be saying 12.7 when the source of truth is 13.0. Now the source of truth will be 12.65 and the Analog Wideband will read 12.7. So when I tune to 12.7 it'll be ever so slightly safer. While messing with all of this and idling extensively I can confirm my car seems to restart better while hot now. I did add an old Skyline battery cable between the head and the body though, though now I really realise I should have chosen the frame. Maybe that's a future job. The internet would have you believe that this is caused by bad grounds. In finding out where my grounds actually were I found out the engine bay battery post actually goes to the engine, as well as a seperate one (from the post) to the body of the car. So now there's a third one making the Grounding Triangle which is now a thing. I also from extensive idling have this graph. Temperature (°C) Voltage (V) 85 1.59 80 1.74 75 1.94 70 2.1 65 2.33 60 2.56 55 2.78 50 2.98 45 3.23 40 3.51 35 3.75 30 4.00   Plotted it looks like this. Which is actually... pretty linear? I have not actually put the formula into HPTuners. I will have to re-engage brain and/or re-engage the people who wanted more data to magically do it for me. Tune should be good for the 30th!
