With Alcazar on my classic wagon

Fitted to see if my lambda is buggered due to a hesitance issue I'm investigating with Harvey.

One installed pic of a simple installation near the vent/a-pillar. Looks neat and tidy and used the electric mirrors as the switched live.



Got three more gauges in the centre pod to fit next when weather allows. Tha ls to Jeff (again) for helping me with my electrical dyslexia (again)

 

where is the afr sensor located?

 

That looks like an Autometer item which takes the feed from a wire on the ECU. Saved my the cost of an engine one of them did

 

ah i may be wrong but i thought the only ones that gave a correct reading were the wideband ones that have a sensor in the exhaust

 

The wide band are better but like i say - as a result of my gauge, i saved a rebuild (possibly). I only bought one to fill the corner pod i had which was made redundant after i bought some Defis. After running it for a few days and it wasn't going solid green like i'd been told it should. As a result, a Scoobnet member offered to plug his lappy in and do a Deltadash run. That showed my car was running lean and after investigation it turned out my maf was failing without any symptoms in how the car ran

 

.......the wire on the ecu is the one from the O2 sensor so it is technically a reading from the exhaust

 

ahh i did wonder, like you say i heard they can save your engine so im looking at getting one. just a vast difference in price between the narrow and wideband versions.

 

I may be very wrong - i'm sure someone will correct me......
The narrowband are nothing more than an indication of what is going one whereas the wideband tell you exactly what is going on?????????

 

sort of what i had read but if it saves the engine its a good thing

 

Its correct in one way,Narrowband reading only accurate right at 14.7:1 air/fuel ratio.They're very inaccurate above and below that.

When you are mapping or you want know exactly what is wrong wideband is better idea,due this mostly mappers/tuners using Wideband

This should help

But still now wideband is not expensive,if you are looking at Innovate LC-1 which now cost little more than Narrowband

Hi guys, yep just a simple narrowband one fitted for the purpose of checking my lambda after having a hesitance issue. It was to see if it was leaning out or running rich when said issue occurs.

Only 3 wires thank god; switched live off mirrors, earth off gearbox screw and lambda wire fed to the back of the ECU. Hardest part was feeding the wires through the frontbofvghe dash, over the steering column/clutch peddle assembly and through under trim to the side of the central gear console.

It's not in a proper pod so to speak but it's a neat simple install and tidy enough. Plus it's another Christmas tree light to look at

 

Andy you can buy pod on the steering column or you can made own one if you are good with fibreglass

Looks good on temporary place

My garage door....nooooooooooo!

 

You need your own thread...

"today I been mostly painting my garage door"

 

I'm disappointed in you Alcazar! The amount of times you've encouraged people to do things themselves as it's so easy, and there you have a garage door that looks like that!!



PS is that your window frame too

 

Couldn't find a steering column pod that would fit. I have my Lamco boost gauge on the left part of the column and didn't want it to look too busy.

 

 

It's A windowm frame: it encloses part of the garden, and was part of the old carport, but I left it standing when I took the rest down.

 

any results yet ????

 

Brun...

where you get that... that's quite nice that is

 

Nerp. Issue is still there and I'm working with Harvey to find a cost effective solution as I haven't lots of ££ to throw at sensors etc. which are absolutely fine.

hi reason why i ask is mine has issue ,is this the hesitation /pulsing issue the 99/00 uk suffer with at 2500-3000 rpm in closed loop ?

was going to purchase a innovate wideband in order to try and diagnose this as most of my sensors are new too.

 

I have two issues really. First one is on cold start up, said pulsing or hesitation between 25-40mph in 3rd, 4th.
Main issue is hesitation around 1800-2200 rpm in 2nd for a split second. Also sometimes in 3rd and around 2000-2500rpm in 1st.

We're just trying to eliminate possibilities bit by bit. Tried two working mafs, fitted this Autometer AFR gauge for literally £10 to eliminate lambda sensor, got a spare throttle body to intercooler hose coming incase my worn one is leaking.

At worst I'll travel to Harvey and have a fiddle about there. He knows I appreciate the time and effort he's put into this thus far, so he's definitely in my Xmas card list

 

Andy what plugs you are running?

Agreed for £10 AutoMeter AFR gauge is just bargain

Have look on older thread from 2004

Harveys good as gold ,watching this thread hoping it sheds some light on mine maybe ?
narrowband will show whats happening ,fingers crossed .,
Bob mapped mine too without my OE lambda plugged in and with it disconnected my car drives sweet as a nut.
fault was there before the map and didnt mention it as i was hoping it would be resolved as result of map..

changed lambda though for a known working one and still the same?,

i was gonna go wideband and use the simulated output for the ecu to see whats going on ???? not sure whats best to be honest.

 

jura,thanks for that,sounds like my issue,

 

NGK heat grade 7 mate. Will look at the link.

Hmm it seems similar to my issue but the thing isn't issue hasn't always been there and the car doesn't feel as responsive low down. The surge at cold can be explained in that link so not so worried about that.
