I would have thought going up to 16:1 would be way to rich anyway and don't see this engine hitting that very often

I think 16:1 is very lean ? , but I'm sure that's what you meant to say .

Wouldn't it be possible to replace the O^2 sensor with a wide band unit ?

16=16 pounds of air .1 = 1 pound of fuel. So basically when u have a mixture of 16:1 it is 4 pounds of air leaner than 12:1. As to using a wide band unit I may be wrong but tuner said that was not an option as yet but will be.

What happens if your o2 sensor dies, how does the edit handle things like this?

your missing the point there lawsy. Street tuner quoted that the factory o2 sensor can re adjust mixtures up to 25 percent either way from the VE table settings.  Pretzel rightly quoted that the factory narrow band sensor is only capable of being accurate between 14:1 and 16:1 .

Thanks

Dont want to confuse anyone further here, but almost every single car made these days has a maximum 20 - 25% correction on the Long and Short Term Fuel trims.

hey tuner yes I agree you have long and short term learning but surely the factory dosn't do its load fuel settings with the narrow band sensor?

just so you guy are not confused with why dont the factory just use wide band sensors well some do but only a few and its not just due to the initial cost but also the reliability a narrow band sensor has a expected life of 12-15000 hrs and a wide band has only 1500- 2000max.

hey obviously I think its fine for the self learn to do so within its range but when it comes to full load I think all you edit users should seriously consider custom tuning as a matter of urgancy the product is fine im just a little concerned about the tunning process?

mind you I will restate that in the only instance that ive seen back to back tests the mixtures seem to be 20% safer than stock mixtures and that is good but I also dont remember them ever being that lean on any other test that ive done b4.

free b4 and after test for a edit user:

conditions you must have a std t no mods.

you must purchase the box and not have opened the packageing or allow me to source it from capa or herrods

and if I need to confirm some more I need to have permision to use another or 2 dynos as well.

I think it will be fine just doint it to get more info! as im seriously looking at being a full on tuning dealer for the edit so I have a need for no doubts just as if I were to use the aps version I'd need there to be no doubts!

Well just get the dealer software and tune every box Nick.......

hey martin that's what id like to do as per previous converations

soon just gotta get these holidays and a few bills behind me and ill do somthing about it already have a few lined up for it

Good on you DW!

thanks as I said id like to do a free test as well for someone just to cure some concerns as this narrow band thingy is still playing on me/my mind!

The most impressive thing about this edit is the fact that you can drive your car to the workshop, hook this little black box up download the pre loaded tune. A couple of dyno runs to check A/F etc. Pay your money drive away, :banghead: no more leaving your car at workshops for Hrs, days or weeks sometimes.

Street Tuner I have a question that I would like you to rely to if possible. Your 10 psi tune is delivering approx 250 rwkw at a faily high injector duty cycle.

In your OP What power gains could we expect to see with larger injectors and better IC?

What boost would you run if you had larger injectors and IC?

How much extra time would be involved in doing a custom tune, if your mods allow for more power gains?

thanks

JB,

Each and every T comes from the factory with an Identical "tune" If the vehicle is unmodded, why wouldn't a new edit optimised to work on an unmodded T be OK?

Methinks some panic + misinformation has been spread.

If you can edit the tune on a dyno, what difference is there between products?

Remember; for the last 40 years we've tuned cars by rotating the distributor (GADS! with your hand!) and by changing jets in the carbies. Not rocket science really.

Less panic of instant detonation of motors please, If you know what your doing, or you've got someone who knows what thier doing, you'll be fine.

Yeah thanks sixfan, that was my understanding, however what then provides the massive differences we see in some T' power output? Surely the PCM must 'adjust' itself to provide the correct parametres etc for that particular power output?
