Did you check the muffler bearings? Also, last time i was in your car; there was definitely a loose nut behind the steering wheel...

Haven't updated for a while not that I've really done much to it lately but did take it out to SMSP South Circuit again and managed to knock off another second off my lap time with a 1:08.26.

i got the instruction manual for the wideband i want to make sure it's going to be useful before i get it.

"The Bar Graph Display (BGD) Range Setting Mode allows you to fine tune the resolution of this instrument for your specific application. With upper and lower set point adjustability, you can set the BGD to utilize the exact range that the engine / vehicle operates within and see exactly how rich or lean you are running in relation to your current set up and tune. Adjusting your BGD limits also adjusts the scaling of the 0-4v data logger output supplied from the gauge. The selected low set point of the BGD Range becomes the 0v value of the data logger output. The selected high set point of the BGD Range becomes the 4v value of the data logger output. Whenever you change these points, the instrument adjusts the data logger output so that the 0-4v signal is always linear between your chosen set points. "

Looks pretty good Theo. WOT input looks interesting, mine doesn't have that. Although the Innovate's have a built in data logger, whereas the Auto Meter seems to want one connected (which is probably the output you'd use for the F-con).

But at the end of the day it depends on whether the tuner wants to use it constantly, or whether you just use one of those ones you can stick in the tailpipe for the day.

My dyno has its own wideband that logs afr to the graph.

I have 2 standalone widebands that can be used for datalogging or roadtuning.

I recommend putting the wideband in for piece of mind, can then see if u have a lean out etc due to fuel surge or fuel pump failures etc

Howd it go today Theo :)

So all ur worry was a false alarm, the 02 sensor reading in the cypher software the Alex was reading from has no bearing on what the actual AFR's are. Tune was fine except for the 1 area which u heard a ping at low rpm high load which was very difficult to replicate on the dyno due to the auto but i found it and fixed it.

Ps, nice single pegger skid when u left :P

Very interesting today Jez- so we know stock ECU > Theos aftermarket computer> motor.

And I can only read what the stockie puts out.

Had a great run coming back down the old Pac- volvo convoy.

Nice :)

Yeah was very weird, especially how much difference there was in the ignition timing output from his aftermarket ecu to ur software

So second tune and no gains? C'mon Theo, slap a Hypergear in there... :P

All the stock ecu does now Alex is run the throttle and cams, nothing else has a bearing other than to keep the MIL away. I have no idea what signals the Fcon sends back to keep it happy but whatever it is, thank you mr HKS.

Jez also found some little parts of the pre-loaded tune that were no so good - and sorted them out.

I've got some logs from the power runs. Might load them if I can be stuffed

That's why I wouldn't use maps designed for other cars, you will always end up chasing gremlins in the tune imo.

Post them up Alex, I would be interested to learn what the Fcon is doing to the stock ecu and that may hold the key. If I end up going down the Link G4 route I may need the same signal bending output maps... The manual transmission will open up a world of possibilities. ;)

Honestly i wouldnt trust the log files as even the timing etc is way off

Exactly right.

As I said it goes Stock ECU > aftermarket>engine.

So Ign timing is not correct for the engine, but other things like Cams, AFM, and BFS are all able to be seen accurately.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
