Turned up today, even comes with a nice big sticker and as the car is 99% track I love me some rice for it.

I found a spare 52mm cup last night so I'll get into mounting wiring etc during the week, need to swing by a mates house and borrow his welder for the bung though.

Think I'm just going to attach it to the steering column, I don't have any other spaces left that don't require drilling and my dash is a nice black unmarked/uncracked one (rare for an old S13) so it's not going there. Stereo gear is already removed and houses an SAFC2 and my oil/water temp and oil pressure gauges, A-pillar already has boost on it so seems like the best place to me.

Will update.

Yeah I think the guy I got mine from is still the has the cheapest shipped price, he's back down to 193 delivered, I got it for $192, it went up to $198 for a bit so we're only talking a few bucks either way.

KEBAB: How have you found it so far?

Hmmm I think I might order one too. I want to also connect it up to my FC-Datalogit.

Good stuff, I've been watching the ebay sale and the price has come back down again, so I may splash out for one now.

How much lag is there between the gauge read-out and the actual RPM value? In the NIStune documentation it warns that the read-out from the sensor might be slightly behind the real-life RPM value, so if you looked at your AFR's on a dyno sheet and you wanted to fix a spike, you would have to edit the RPM points before the point where it is on the dyno...

Aaaaaaaaaaand I've confused myself with my terrible explanation :unsure:

cant remember the figures but the lc-1 manual has some stuff in it about lag times and what it should be set to for certain distances from the head as the innovate software has built in correction for this which is adjustable.

Well I had an interesting time last night getting the gauge installed, welding the bung in tonight so the sensor can be hooked up.

I couldn't get my gauge to power up, this was for two reasons.

1) Despite the manual saying it wants a switched 10-18v source, it would not power up when connected to a shared circuit (that has other gauges on it) This was testing around 10.9v. I had to wire it up to another circuit that was testing around 11.8v.

2) The 4 pin connector that supplies the power/earth and gives outputs for the 0-5v analogue signal and the digital signal for data logging would not make clean contact with the pins on the gauge, I had to use a scribe and lightly bend the prongs inside the connector as well as slightly angle the pins on the gauge to make clean contact.

After that it powered up no worries.

I'll have some more info after I weld in 02 sensor tonight. I'd also considered lag as the manual states you need a good 36inches from the exhaust port on a turbocharged or high rpm car, which mine is so that puts the sensor pretty much on my de-cat pipe so I'll also be using the cat sensor hole to bring it into the cabin.

At least the sticker went on with no hassles...

Update time.

Welded the bung in last night and ran the sensor wire up through the cat sensor hole in the floor through the centre console and up behind the dash, what a fun job that was. I had to remove the clip from the gauge side of the sensor wire harness to fit it through the hole. I wrapped up the joined connectors in race tap and hid them away inside the end of the chassis rails to protect it (I mounted my sensor on the de-cat pipe, more on this below).

As the manual states, you should aim for 36inchs downstream from the exhaust port on a turbo or high rpm engine. This would have put me just on the edge of my front pipe but seeing as it's so nice compared to my de-cat pipe and the de-cat pipe is easier to remove should I need to I went for this location.

One thing I did find is that having it that far downstream does introduce around .5 of a second lag in the readings vs throttle input, bare that in mind when tuning. I'm not sure if AEM's tuning solution offers compensation for this like the Innovate apparently does.

If you intend on watching the gauge from your peripheral vision I'd suggest mounting it at your eye line height on the A-Pillar, the gauge readout and coloured LEDs are too small to read easily without looking at them directly, though you may be better at concentrating on the road and keeping tabs on your gauges than me.

Info wise it has confirmed my assumptions, a little rich down low and a touch lean up high. Great to have that sort of data readily available.

I'm having AEM send me out a new 4 pin harness (the power/ground outputs lead) as two of the pins in mine didn't make good contact and I had to modify it, I've already got it working but I'd rather have a new spare on hand.

In the pics below the car is not running so disregarding the reading.

Looked like mild to me, welded into mild pipe and no issues at all. Can't think of how this would be an issue on a stainless pipe.

I just dropped a hole saw through the pipe that was a touch larger than the bung so I could recess it in and get a bit of angle (manual wants minimum 10deg to stop moisture build up) Plus I needed some extra clearance.

Aaaaaaaaaaand I've confused myself with my terrible explanation :unsure:

I've had my innovate hooked up for about 3 or 4 months now. You dont need an extra hole in your dump!!! It plugs into the stock location and has 2 outputs. One for the gauge and one is a narrowband signal that you can use for the ecu to keep it at stoich when cruising. Both outputs are fully configurable. I've got my wideband talking to my datalogit which is actually a bit useless seeing as the datalogit can only give min, max, or average values. With my girlfriends help I managed to tune my car extremely well using the datalogit for knock and the wideband for fuel. You dont need a dyno to tune your car. My tune was 98 percent of what the dyno guys could do and I would have got it to 100 percent. I just had other things to do besides tuning every time I went for a drive. To answer your question straight up, any lag time that is there is almost nothing and wont affect your ability to tune it properly.

    • Yea that’s why I said ima test them with multimeter and see the reads.
    • Only at idle. Isn’t a problem when rev it seems.
    • @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?  
    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
