Been away awhile (few days) this must be the first time my build threads been 4 pages down the most recent list. Good times!
So had a sticky rear brake caliper I've noticed since I've been on the brakes alot tuning.
Decided I'd try my luck and fit new slider pins as I dont fancy paying out for new calipers yet.
Still have sticky calipers... lol
Got my new wideband, it's a portable unit so it's easily transferable between cars and does all fancy tricks like datalog, code reader etc I got this to test the aem wideband.
Innovate lm2.
Turns out after I dunked the aem sensor into a can of petrol whilst hot it now reads correctly....Or atleast close enough.
I've got datalogs of the old tune reading 10.5-1 before I even added 10% extra fuel whilst I was testing. Now it reads close to 11-1.
Either way I'll continue the tune on the new wideband to get used to using it.
This week's issue however has been knock monitor related.
Quick background on what the monitor actually does...
Essentially it's a stethoscope for an engine, I'm listen for a tick/knock/ping noise that's characteristic of detonation(kills engines fast) now I've been getting a noise very similar to this but due to the overly conservative tune I'm running atm I know for a fact it can't be detonation. This leaves me stuck for tuning the ignition timing because if I'm getting a false reading through the headphones now, how will I know what a true reading is?
I've tried everything over this past few days to try and clear this static type noise that comes through the headset from around 6k upwards.
Very frustrated yesterday because I was sure I'd tried everything I could think of. Then I tried something new today, basically the unit has a setting that you can use for really noisey race engines. So I gave that a shot on my conservative tune and the static noise is completely gone! Just beautifully filtered engine noise through the headset! I've not tried inducing detonation yet to confirm I've actually fixed the issue but quietly confident as that's the first time I've had a completely clear sounding run through the headset. Tomorrow I'll be getting a little more aggressive with it on low boost and we'll see how it goes. I've got rough figures in my head that I can use as a guide so fingers crossed!
I've also noticed I've built up a far bit of equipment already lol
