Big Thanks to James at Auto Dynamix
 

Would just like to say a big thank you to James at Auto Dynamix.



His attention to detail and service was superb. I have learnt a bit more on Cossie's today after meeting him.



I had issues with my alarm wiring on my Cossie. Sorted it out no problem.
He also went to check the car over, ECU and its Engine loom wiring and checking the sensors, finding my TPS needed adjusting and sorted out the fuel pump wiring which he found to be running hot at the relay due to some cheap crimp connections I used when I fitted my new fuel pump and filter a couple of years ago.

Also told me some items that needed addressing after a quick spin around the block.
I have been lucky not to have had a melt down after he checked the readings advising me on what I will need to do, so for now no revving hard over 5k :wall::cry::cry: as she was leaning out on my standard Blues and T34 set-up. So time for some Greens, 3bar Map Sensor and Chip.

Also thanks to Jason Dale for the wets and grub

You have the same problem i had with my fueling. Hopefully you will get it sorted. You need a air/fuel gauge fitting to your car

I hope he does really well its hard starting up on your own especially in these times

From my experience with James he has been spot on. He has always helped me out on pf.

I have a Narrowband Racetech AFR meter and he says it is not ideal as it reads wrong at certain points. Yeah I could get it sorted but the boss will murder me if I bought a greens set up. :cry::cry:

I always though A/F gauges would read right.

Yeah but mine is a narrowband one he said I need a wideband one.

Narrowband simply shows if you are rich/lean from stoichmetric, but not an exact AFR/Lambda reading... basically useless.

Most widebands are not that accurate either.

What is a good one Mark??

This one forget about the rest.

Mark

But just to add dont buy the ls4.2 sensosr option buy the ntk sensor

Thanks I forgot to say that:grin:

Mark

Are the stack afr gauges any good was just about to order one!

Lee any wideband with a ls4.2 sensor will not be that accurate and the stack has that too . the problem is they are far to slow but the one that Mark has put up a link for with the option ntk sensor will be spot on

Ok thanks for that good job I didn't get one then, il have a look at the link above and get one of them then.

So why do many tuners/rolling roads use innovate stuff?

Surely if its all crap then why are we not using this magical gizmo from the states. Which i guess 90% of us have never heard of?

Paul

Ive got an innovate gauge in mine too. I thought there were good??

Quite honestly I dont understand why tuners are using a cheapo wideband ! When you put a ls senor along side a ntk you see the difference the ls4.2 sensor is so slow to react to changes it is actually quite shocking against the ntk sensor

Thanks for the kind words Ben, glad you were happy. Hopefully see you again soon to resolve some of the issues we found.

The new innovate LM2 uses the 4.9 sensor, seemed quite acurate when I compared it to the ECM at Motorsport Developments so I'm trying one of them at the moment, I think I will head for an ECM long term though.

Yes mate. Once I have the funds for the Greens etc I will be back :top::top:

will have to look what sensors i have not sure if they are bosch or ntk. Used to work for honda and their diesels use widwband ntk sensors.

Oh btw James hope all is good and the family are well.

Paul

Innovate claim they are the most accurate and they are a u.s based company but tbh they are all prob made in china lol.
so the ntk sensor is faster acting than the bosch. If so do they use the same multiplug?

Yeh honda use the ntk sensor Paul but you will need a controller that works with a ntk

Just to ad some are fairly accurate BUT the issue is in fast changes they can not keep up so when logging you can clearly see how slow the ls sensoe equipment is compared

I will have to look. As i have a lm2 also.

I have a lm2 in a posh case with some extras ob2 iirc been out the case twice lol a £300 ornament

lucky for me i didnt pay full price for mine. And also have a LC 1 in the saff.
But as im not mapping or logging id guess its ok.

Mark is right. The NTK has always been years ahead of the Bosch.

We have been using ECM for our mapping AFR tools for over 12 years now and they only use NTK Lab grade sensors. They are simply outstanding. I now have it hooked into the dyno cell for our day to day mapping as the Bosch one can be hit and miss at times for reliability.

Be aware NTK make three grades of sensor. Even the cheapest one is far far better than any Bosch one but the lab grade ones we use are incredible. (And at over £500 each, so is the price) They read from 6 to 150AFR (Lambda 0.4 to lambda 10) with less than 1% error from one end to the other. Incredible.

All that said, for "Monitoring" of AFR I dont see any problem using Bosch LS series really. The difference in accuracy is kind of here nor there if your only looking to see what your AFR is for in car driver monitoring.

The LSU4.9 is also fast, fast enough for most applications. A lot of controllers also add a time delay as they average readings, so much of the delay you will see in datalogs may actually be down to the controller rather than the sensor.

There isn't anything special about calibrated sensors, they just test a batch using cal gas and hand pick the sensors which are within a few % of ideal. Lab grade sensors are another story.... but so is their price.

This is a good read:

The unit with the lowest latency and highest accuracy was surprisingly the innovate XD-16 which used a Bosch lsu4.2 sensor, the PLX unit was also good, their 'tuner/dyno' grade unit uses an LSU4.9.

The NGK AFX which the Ballenger Motorsports AFR500 unit is based upon was actually middle of the pack. Low latency (delay) but an accuracy of +/- 1AFR!

I have done quite a bit of testing of various wideband units and lots of research and tbh nothing suggests that the NGK standard sensors are any better or faster than the 4.2 or 4.9, and not many people will like the price of calibrated sensors for use in a road car :( Also worth noting that a huge number of wideband controllers use the Bosch CJ125 or similar control IC so are more similar in performance than their marketing blurb would suggest!

I quite like the AEM UEGO range, they are good enough for 99% of road users needs and couldn't be simpler to install, they are also under £150!

I haven't had my grubby hands on a lab grade sensor yet, but from what I have seen/heard they are amazing!

The thing I like most about the LM2 and even LM1 is the suction cup window mount, means you don't have wires all over the place and a loose gauge flying all over the car :cry:

They look good value for money, I dont have a reliable AFR meter now the dyno has gone and needed something to use on the Firenza so I've just ordered the one with the $150 NTK.
