This forum is where I go for research. So is someone new suppose to guess everything?

So the E40 is definitely missing some tables to adjust the narrows functions? I am not familiar with any of this so the tables you are referring to "proportional/integrator delay tables" are used to...

Eaglegoat, thank you for all your help. I have attached my latest tune. Are there tables in my tune to calibrate the narrow band sensors? thanks Russell

It looks like there could be...

Thanks 02statesman, I will have a look at that.

Will15, apparently your narrows can be adjusted. I don't know how to do it but someone on here will be able to help you. If your wideband is correct then adjust your narrows so they read the same as...

If you find that after tuning on the dyno and then driving on the street that your tune is a bit lean then this is fairly normal as the heat and load on a dyno is different to driving on the street....

schpenzel, I have trouble spelling your name lol . I have read that thread before and read it again last night. I don't seem to have that issue of richness after a flash maybe because we tune in...

Eaglegoat, we tune VE first in open loop and then Maf in open loop using my wideband which is fitted permanently. All tuning is done in lambda. My maf is a made up 100mm aluminium pipe with a Ls7...

Thank you very much. I will read the link

Did you mean "enable closed loop" and can you explain why this happens? I always warm the engine up for 20 mins minimum before even looking at the wideband. thanks Russell

Schpenxel, I just read your new post which is quite interesting. Most gen 4 engines have a 58 tooth reluctor and mine has a 24 tooth being sort of in between gen 3 and gen 4 being the silly E40 ecm. ...

Schpenxel, My injectors are siemens deka iv 63 lb @3 bar or 72.9@4 bar. We got the injector data from greg banish's dvd injector data. Scaled 24% of course. I have a NGK AFX wideband fitted to my...

Anyone care to comment. Russ Kemp or Dave Steck or Mowtown maybe?

I forgot to mention that the ECM is a E40 and the engine is fitted to a Landcruiser utility running a T400.

Any gurus like to comment? lol

I was wondering exactly the same thing.

So what we have here is scan 5 which shows a leaner log, probably at lower speed mostly and at the end scan 4 which is on the highway and in the middle my tune.
...

My set up is Ly6 block 404 cubes , Harrop 2300 blower , Trickflow 225cc cnc heads, cam 226/[email protected]" 114 Lsa .600 lift. My tune so far is a MAF SD tune and is of course in open loop at this stage....

we did set the VE at idle first and then tuned the VE. Idle I found is a bit of a behavioural guess. The Wo2 swings a fair bit as there is not enough constant heat and pressure to stabilise the...

Well basically we tuned without it and we are just trying to head in the right direction. The tune above is obviously a MAF SD tune atm and my next question is whether it would be better to use the...

Thank you for all your help cheers

I have read 5 litre eaters thread and after the tuning we have done I have no hair left. lol

hahahaha , We are all glad that you think you are now a pro tuner. There is always more than one way to tune I suppose. I was after a proper opinion and that is why I ask the experts here. I know of...

Thanks Ed

My scanner has filters on it for road tuning to get rid of decel fueling. The only other thing the engine does now and again is it dips slightly in revs when I pull up at idle to about 800rpm and...

I hope this worked . It should be a matching tune and scan .
I haven't uploaded anything for a while. The 4.hpl at the end is the scan. The file ending in 8.hpt is the tune
