Good work fella hopefully I can hear it at bills next Sunday :)
Good work fella hopefully I can hear it at bills next Sunday :)
At Goodwood I passed the 100dba static test NO problems at just 86dba on the old system, but I was very close to triggering the drive by monitors at 100dba existing the chicane at the end of the lap.
I'm home again this evening, and will be doing some logs tomorrow morning to see how it compares to the old engine :)
I'm currently very keen on getting a wideband AFR gauge in the car, with the ME3.8 EcU being prehistoric as we know (bloody thing runs on coal!), there's no guarantee that in the event of a problem the car will do anything to protect itself.
Niki advised some time back that when pushing the car any further it would be a good idea to fit one, so I think it's time.
Currently deciding between the AEM UEGO:
AEM Wideband O2 UEGO Gauge - Monitor Air/Fuel Ratio with the Digital 30-4100 - Wideband O2 UEGO, Water/Methanol, Stand Alone Engine Management, Piggyback F/IC, Tru Boost Controller, Gauges, Automotive Performance Electronics
Or the Innovate MTX-L:
MTX-L Wideband O2 Digital Air/fuel Ratio Gauge
I think the AEM wins it though, as I can get one from Xenonlv on ebay, who gave me fantastic service with my AEM WMI kit, it';s AEM which I already have products from, and it lights up red which matches the dials.
A wideband gauge is on my list of to buy aswell, though I have been looking at the Stack AFR gauge, partly because (I know this sounds daft) but i want it to match the oil pressure and boost gauges:laugh: But it also has a programmable alarm to warn of running lean, which could be handy and save having to keep watching the gauge.
That AEM one looks good though.
lmao at "too fast and scaring other track users!!!"
I like the stack one very much.
My wallet doesn't though, and that drives the decision :laugh:
OK, decided not to wait any longer.
AEM Uego and 52mm dash mounted pod ordered!
I need to get one of these as well....im tired of spending money on this car
Do we need the Wideband cable
Aem Water Methanol Injection Kit 1 Gallon 3 8L 30 3000 | eBay) the latest version from AEM with the valve issues etc sorted?
Sorry meant Wideband uego replacement sensorQuote:

Mine's been absolutely great though, I love it.
Ive got two innovate AFR's the MTX or whatever it is isnt happy with VAG cars turning off the injectors and the probe regularly over heats
Cheers for that Paul, even happier I went with the AEM now then :)
i'm going to be fitting some camber and toe shims tomorow, and wanted some advice.
I'm sorted for the camber, and will be evening out the manufacturing differences and setting it at 2.2 degrees negative on both sides.
For the toe, I currently have 0.17 and 0.26 degrees of toe in. L & R respectively
I have shims for both 0.13 and 0.25 degrees toe change.
Should I fit a 0.13 shim to each side, reducing the toe in but leaving the minor (within tolerance) factory inaccuracy.
Should I fit the 0.13 shim to the LHS bringing it to 0.04 degrees toe in, and the 0.25 degree shim to the RHS bringing it to 0.01 degrees toe in.
Fitting the different shims gives me more even rear geo, but somehow feels wrong.
i toe out on badgerwagen
I would fit what corrects the settings. regardless of them not being a "pair" to me would seem daft to ignore the diffrence if your changing it?
Been tinkering with this one over here...
id fit odd shims bringing both sides to as close to parallel.
you got toe out on the front?
I've been out and taken some logs for you,
The old setup, with 12psi actuator, was peaking 172g/s on Actuator, and 185g/s on full boost.
The new setup, run on actuator at ~15psi
187.15g/s, on actuator pressure! and a few other pulls where I didn't quite rev it out and it's made 185g/s
So, whilst I know it's not conclusive, it's flowing more air now on the actuator than it did previously on full boost.
Also showing zero CF's across the board, and IAT's are nice and low
Very promising indeed!
Worth noting that I'm using an OBD II vr6 MAF housing (80mm OD) with an AGU sensor which is 70mm OD, and all other values are scalled to suit, so my MAF readings are around 38% low from the logs.
The AGU sensor can only read a max of 187g/s with slight corrections for atmospheric conditions, so I've basically maxxed out the sensor on actuator pressure.
This seems a little odd to me, as Niki reckons the AGU sensor in VR6 housing maxes out at 320bhp!
Very nice MR.Prawny...:arco:
Gauge holder for the AEM AFR has arrived, so I threw an old boost gauge in to try out a few different locations.
I was originally thinking of putting it next to the boost gauge, but then decided it might look crap.
Lining it up there, I think it actually does look OK, and it's line of sight in an area I'm looking anyway:
So this is option 1:
Option 2, on the column, my DIS doesn't work anyway, so I'm not missing much:
And option 3, the least favourite, as it's on it's own there, and I'd have to drill a hole in the dash as I HATE visable cables anywhere:
Thoughts please people?
Option 2 or get a double gauge holder for your a pillar.
Cheers Joe, I don't like double pods on the pillars, it just looks too bulky, and I'm proud of this one as I made it :)
Option 2 is looking king, with the black facia and bezzle on the AEM like this:
I like it on top of the steering column. Looks pro.
I'm trying to find a guy called Jarvis, I don't remember his username, he put his boost gauge on his steering column, but he moulded around the gauge to make a custom pod, I'm sure he posted a pic, he drives a LCR.
Found it, he stuck his liquid gauge in there! lol
Prawn, I've recently made a pod for the steering cowling. Like yourself, I'm not keen on the pillar pods. I bought a newsouth pod for a mk4 golf, is perfect position for a gauge, but the newsouth thing doesn't fit properly so I adapted the standard cowling
Prawn go for the steerig coloumn, i got a custom made 2 slot one off andrews mate, looks mint and helps you monitor the gauges better.
Steering column it is :) Munch - that looks good mate. I like. I'm going to mount the single on top for now, then if I get any more gauges I'll mount them side by side.
Had a bit of a chill out today and went to Newbury with Tori, bit of shopping and a Costa, then back home and there was still some daylight left, so I decided to make a start on tomorrows work.
I dug these out from my box of new parts awaiting fitment:
And these out of the boot of the car, KW V3's :)
Quick check on the ride height before stripping it down:
Old dirty Weitecs ready to remove:
and thanks to my impact gun, 10 minutes later it was out:
Eibach offset top mounts built up onto the KW V3's
All threads and the base greased up and ready to fit:
And in it goes:
Turned the car round, now you see it:
Now you don't:
It took literally less than 5 minutes from jacking the car up to having the coilover out - did I mention how AWESOME it is having an impact gun?
KW all stripped down to grease up the threads:
And in it goes:
Very hard to make it show on a picture, but it's made the car look quite different in how the front end sits:
Went for a little drive and all feels great, stuck £30's worth of V power in it and did a few more miles then pulled over on a known level concrete surface and checked the cambers with my phone app:
Not too bad at all, obviously that's just a rough guide, but it's feeling amazing so far. I've set the mount sup to that the caster and camber is increased as much as they can give, so the offset of the topmount is at 45 degrees inwards to the rear. I could give them more caster, or more camber, but this is the most I can get of both together.
And on a totally random and seperate point, Jardo did this little photoshop earlier, which I think looks awesome:
Rear coilovers and camber shims coming tomorrow!
Pdogs, I think you should mount the AFR gauge on the column too. It's the most OEM looking location you've got left.
I did that photoshop with one of these -
By laying the old picture underneath and then using pencil strokes to mimic it. Took ages but was fun, if anybody else wants one done then send me the pic and I'll give it a go :)
What you doing with the Weitec's? Are the ****ed?
Hell. pen and paper. There's a rumour we might get some in Cornwall within the next twelve months. Will make life so much easier. Also NICE to see, to see you NICE.
I don't really understand how this guy can make it work. But it involves inserting a control box between the car's harness and the gauge cluster. Here's a link to the photos I took while installing it.
At first I was really disappointed by those numbers. But the fact that they're skewed by the sensor/housing mismatch explains everything. I have a spreadsheet which studies the voltage response of these sensors. It works out that the scaling factor changes slightly as airflows increase. It starts out at a 1.38/1 ratio but drops to 1.30/1 by 5000rpms or so. So, realistically, your actual flows are somewhere around 185 x 1.30 = 240 g/s.
That is really solid performance at 1bar of pressure. :applaus:
Thanks Doug, would you be able to share that spreadsheet with me? I was working on the 1.38 rule for scaling, but it would put my maf readings in at 258g/s in Real terms, which I thought sounded TOO high at this stage. 240g/s sounds much more realistic, and ties in with Niki seeing just over 300bhp at 1 bar on the old setup also.It'll be on the dyno at Bills in a week anyway, so we'll have a better idea then, and when I get the chance and some time off work ill head back up to Rtech and we'll see what it can really do!
