This has been the best thing I ever fitted performance wise!

 

The mid range is to die for! If you don't have one buy one;)

Iain,

 

Who fitted your Air/Fuel Controller?

 

Does it have settings to help avoid detonation and how does it work? for example does the unit know if the fuel mix is leaning off and can it compensate by increasing fuelling?... these fuel ratio controllers fascinate me but they got to be a little scary if they are not set up right no?

 

Does it display fuel/air mix levels on an dash display? - I used to have one on my old 300zx but never dared switch in on;)

 

interesting....

Latz fitted this and the car has NEVER ran so good I SWEAR!

 

Detonation is usally the cause of bad fueling, When latz fitted this he set the fueling to increase by 1% all the way up the rev range.

 

Too right about the setting up,If you set this up wrong the results can be serious engine dammage:(

 

There are big companys out there that have failed to set these things up in the correct manner,who I won't name on here;)

 

It has a display that you can veiw the RPM or the % of the fueling.

 

 

 

Just remember one thing;)THE ART OF GOOD TUNING IS ALL IN THE FUELING:)

 

 

Give Latz a call he is the expert on them,this is his direct line,afternoons only LOL 01942677552

Was thinking about getting one of these as well, but there's nothing it can do that you can't do with an Eprom programmer and some knowledge of the fuel maps. Works out much cheaper to do (£50ish).

Added benefit is that you can play with the timing, set up for dual MAF etc. as well.

John had the ECU mapped 3 years ago,I thought the car was quick until I fitted one of these.

Basically though, the chip wasn't correctly mapped - thats why the AFR had such an effect ;) If the chip was correct, the AFR would have only messed up the fueling.....

Ok shit head,ask Vinz he has the JWT chip and it made an even bigger increase with his car.

 

So now you saying JWT are shite ?:rolleyes:

LOL don't get me wrong I aint havin a dig ;) The point I was making is that if the ecu is set up correctly, then the afr will make no difference - it can't make a perfect map better. The chip Vinz has will be an off the shelf type - these are set very conservatively so yes - in that respect they are shite compared to what you *could* get out of them. What John is talking about is doing the same as the afr does BUT doing it by changing in the ecu maps.

Not having a dig you! yea right LOL you have fookin badgers claws for finger nails:DHey I know what John is talking about!

You tell me who in the UK can set with perfection the fuel maps on a 300ZX???????????????:rolleyes:

Basically the point being made is the Sucicide Engineering chip is KAK :D

LOL and JWT are even Kaker:p ,And please tell me what Sucicide means LOL Is it someone that sucks cider:D:D:D

errm lol i cant help you there :D

 

I agree JWT ie very of the shelf safe, SE is obviously mapped to each cars spec (albeit with no knowledge or chip tuning :D:D)

 

So what did latz say? your car was leaning out over hi revs?

or higher up in the gear range?

no chip, even the std one, is going to be a perfect match for an engine, esp when you have bolted all sorts of other stuff to it, too many variables. A custom map/ECU or a base chip and some tweeking device set up properly on RR and the road is the only way to ensure proper fueling.

 

A certain make of ST 2 chip for the S13 is absolute poo, I couldn't give mine away. ;)

Which is EXACTLY what I was saying ;) However with constant access to the facilities to reprogram the ecu chip, a perfect map FOR THAT PARTICULAR CAR could be achieved. Then no additional devices would be needed :)

Well I'm glad we all agree on that then ! :D

Well apart from the Cider Suck that has lost me:D:D:D

JWT v SE

Auto V Manual!!!

Its just like the old days on here. YEEEHAAAAAA

Bring it on baby :D

Paul

wasn't their an ECU that was constantly updated? or am was i thinking of something else

Bloody hell Mac, do ever wish you kept yer gob shut :D

some people just don't like it when they know yer cars getting quicker again :D

Seriously though, i've got the SE chip and had an AFR installed about 2 years ago and personally i go with Jezz on this, you could fanny about for ever perfecting yer chip to suit yer car today add another simple mod tomorow and start over again, plus you'll never find 2 car engines the excat same.

I like the AFR cos it alows you to FINE tune the fuelling at the push of some buttons to extract the most it can to suit yer individual engine, plus it also has a feature that quickens the throttle response.

People for years have argued that certain mods are awaste of time or money and i'm sure they will for many more ;)

cheers

smithy :cool:

Too right Smithy;)You know I am talking sense because you have had the same done yourself.

 

You were also pleased with the SE chip am I right;)

 

Anyhow for those that think the HKS AFR is Kak it is their loss eh bud;)

May i be struck down in flames for this, but yes the SE chip is good ;)

cheers

smithy :cool:

I had an SE chip in my car. It was much faster than my friends JWT Equipped car right up till the point my engine gave up due to detonation at 5k at 13psi. :(

Bloody 'ell, opened a can of worms here alright!

All I'm getting at is that the AFR does nothing except change the MAF signal going to the ECU, thus shifting the ECU fuel enrichment value to a higher load point on the map. If you know how much it enriches by then you can change the map to the same value that the AFM fools it into giving.

Also, the AFR can't extend the maps, so unless SE did it, once you go past the last load point (about 13psi) then the ECU will always attempt to make the same AFR no matter what signal you give it - probably why you see midrange gains and not too much at top end. Not saying it's not handy for tweaking in real time, but is usually set then left alone, which gains you nothing over a correct map.

I'm not surprised you can make gains over an SE chip if it's mapped on the road as I've heard, you just can't get it right that way. It took about 4hrs solid on a rolling road to map my 205 properly.
