Hi Mac.

I am confused. Is your MS set to read and tune from the wideband all the time normally?
My MS isnt even connected to the wideband (or the old lambds for that matter).

I tuned mine on the fly manually then burn to the ECU..... done.

When is a good time to pop by Friday? I want to be at Mallory at drinks o'clock tho
Hiya bloke,
Seems I 'may' have other issues so won't be taking car out. I'm in Oxford am and back around 2ish, Your welcome to pop by after that mate be good to see you. beer

The EGO controls the Lambda authority ..Mine is set at 15% .Why not turn the EGO to 0% to see if the smoke goes ..

Has anyone thought about fitting one of the modern type MAF units for ultimate fueling for low speed and cruising then TPS for acceleration enrich ?

Any pitfalls doing it this way ..

Yeah your putting a restriction back into the intake, you don't need it. Just tune the ECU, you should already have a TPS set up

Hi everyone im new to the site so forgive me if this is the wrong place...

I used to do some mapping a few years ago.... Is there a piece of inexpensive equipment i can buy and do it myself?

whats the best method? Ive heard you can only alter the fueling etc via two chips, can anybody supply me with these? Obviously i will pay?

Thanks

Steve

If you are on the original 14cux ecu, then its a no go as far as diy mapping goes. You will have to contact a Mr Mark Adams.

Anyone fancy sharing their AFR target map for speed density?
Now I've got mine running really well on the original Alpha N + compensations map, its time for me to write a new map using MAP as load.
I would be interested to see what AFR's people are aiming for on normally aspirated and boosted setups, and see how it compares to the Alpha N

Yes it is and for the life of me I can't understand why the guy who mapped it originally would have used A/N for a blown engine? It should have been speed density!
The trouble with adding compensations is when under boost the whole map gets a percentage of extra fuel for a given kpa boost pressure which isn't very accurate!

Yes Daz that's it, how do you find it runs? Is there any low speed shunting or slight hesitation on tip in?
this is mine on my DTA

from 1 to 14 is throttle position as a% 1 being idle 5/6 being cruise 9 being 100 KPA and above that are in boost.
im in the process of changing the load sites to KPA as load using a combination of data logging and DTA's version of Auto tune, hopefully will have something resembling a good map by the end of the week

Its very good but I would make the 15.5 to 15 afr for safety.

shunting is close to zero ,the only place I would like it to b e a bit leaner is around 50mph in fith but then it might be to weak at lower speeds.
This is the one Rob did for me.

I shouldn't worry the 15.5 on your first map is fine your engine will very rarely see below 20 kpa and there is no load around that part of the map, its in the over run area so you save a little fuel when you let off the throttle, mine was seeing 18 afr in the first column when my foot was off the throttle and winding down, I've gone to 16 only because the DTA only goes from 8 to 16 afr.
Also at lower speeds your going to be in a different cell than when your on cruise as your kpa will be higher when pulling away or low speed low revs as a posed to hi speed medium revs.
My idle kpa is around 65 and on cruise it's 40 ish on over run its as low as 20, and when I press the loud peddle I've seen 16 psi of boost or 210 kpa

I'm a serial tinkerer, I'm very very close to my map being bang on albeit the ignition on the safe side, I've made a set of det cans to detect detonation which I intend to use whilst road tuning.
I've not lost faith but not many people like mapping DTA for some reason?

Had the Megasquirt for a while , I don`t have a clue how refine ,tune etc ..scared to death of the thing .

If you want to tinker with it just make sure you save the original to a memory stick and if you can password protect it, then you can always revert back, I'm not familiar with ms but the dta you can play with the software on your laptop without it connected to the car.

Buy a pair of these

And a pair of these

Drill a small hole in each ear defender to the stethoscope fits in nicely into your ears, then get two ring terminals to fit the block knock sensor threads and solder some pipe to them avoiding the manifolds, then rubber tube up to the bulkhead grommet tee together and thread it into the cabin then when you want to use them connect the stethoscope][url]
