Haltech Haltuner, any opinions?

[muaythailuke]

Hi,

Does any have one of these installed on there car or ever used one? Just after some thoughts on if they are any good or not.

[Russco]

I was going to put one on my car but my tuner didn;t rate them - said I'd be better spending the extra $$ on a wide band UEGO type one, such as AEM, Microtech etc - priced them but they cost a packet.

Haltuner uses a narrow band O2 sensor.

So that makes it effectively usless for anything other than seeing when the ecu is in closed loop operation.

Yes I have one of those and it works very well . I got the Haltech people in Taren Point (Syd) to test mine along side a Uego probe of theirs some years ago (on their static 1GGEU test engine) and the readings were virtually identical .

I used it for years on an Autroniced FJ20ET powered Bluebird with great results . The Haltuner is not the tool to tune engines on the bleeding edge , but it has more than enough scope to tell you if the mixtures are reasonable or getting out of hand . Its a fantastic thing to have permanently installed to give you an idea whats happening ALL the time . If I was made of money I would have the Autronic air fuel ratio meter with the Bosch 4 wire probe , people trust them and they give a numeric rather than LED read out .

For the cost the Haltuner is probably hard to beat .

Cheers A .

RB30 Power I think you'll find the supplied NTC probe is wide band , mine read from about 10:1 to above 16:1 .

Cheers A .

Yeah well the cost of mine was pretty good, cost me nothin :headspin:

I also got the O2 senor to go with it but doesnt look like your normal o2 senors, it hard to eplain what it looks like so ill take a photo and post it up. Im thinking it might be a 4 wire probe like your talking about???

So you think it would be a good idea to install it to keep an eye on things when engine goes back in after rebuild?

Thank guys

Well i looked at these the other day briefly.

As soon as i seen the price, something like $300 odd, i knew it had to be narrow band based.

And further research on the net basically confirmed this by owners of this tool.

Lastly i found this on the ECU manual from Haltech relating to their haltech haltuner

The Haltuner is an inexpensive air/fuel ratio indicator that gives a full-scale deflection from rich to lean over a display of 30 bar segments. It is compatible with all Oxygen Sensors that output a 0-1V and can be configured upon request for other sensor ranges.

Since when did widebands come with a 0-1V output.

Sure they thing can read a 0-5V wideband, but you have to get Haltech to reprogram the bloody thing.

Basically you wouldn't want to use it for any sort of forced induction tuning, unless you know it is setup for wideband sensors. Then you have the heater elements inside widebands that have to be accurately controlled for accurate readings. I somehow think the $300 Haltuner lacks some of this logic.

[discopotato03]

I don't want to get involved in an argument here but I know what I saw with my own eyes . The NTC probe I have I bought with the E6 computer in about 90 - 91 . Much later I bought the Haltuner which if memory serves me correct was around $235 trade - not including the probe which I already had . The NTC probe is heated and I think four wire . As I mentioned I got it tested in tandem with EFI Technology's own Uego equipment because I suspected my probe was poisoned .

If you can find him Justin is the man to ask , I believe he left EFI Technology some years back to start his own aftermarket EFI fitting and tuning business .

Anyhow I tuned that FJ20ET with 550 cc injectors to give 27-28 mpg , good hot and cold starting and smooth transitions - good manners and no closed loop correction . I put a lot of that down to the Autronic SMC's fine resolution and charge temperature management , but it didn't tune itself (pre autotune) and the Haltuner was the only AFR measurement device used .

Having said this I do not suggest people should tune their own cars on the street , I had a bad experience with a chassis dyno operator who cooked my no 4 piston and was using Autronic/Bosch 4 Wire equipment - cost me 5 G's . After that I did my own using MK1 eyes and ears and a Haltuner . The car was daily driven and it was in my best interest to get good fuel consumption . I also switched to a button (padle) clutch and as everyone who uses them knows engine response and part throttle torque needs to be the best it can particularly with lowish 8.5 CR . As I said before it worked well for me so was good value .

My opinion only , cheers A .

My 20 cents.....

The LM1 wide band A/F ratio meter is a better buy for not much more cost. Noting that the cost of wide and fast lambda sensors has dropped considerably as there use becomes more common. Ditto the cost of meters for utilising the lamda sensors.

Like discopotato03, I have tuned a car using a narrow band lambda sensor for maximum fuel economy, idle and off idle stability. The A/F ratio I was aiming for (for best economy) was in the range that the "narrow" lambda sensor covered with some accuracy (around stoich). Also the lambda sensor was "slow", meaning that its reponses to changes in A/F ratios was not instantaneous, it took a little while to record the movement. This is obviously not a problem when tuning for economy.

But (there is always a but), when tuning for power and response, I don't want stoich A/F ratios and the changes are rapid, so I can't use a narrow and slow lambda sensor.

[discopotato03]

The LM1 , I'll do a search on that one . Agree with the high cost of good equipment in the early and mid 90's . My reason for parting with the Haltech and Autronic computers was I wanted something that could load sense via a mass air sensor rather than MAP . I feel there's to many air temp correction advantages to pass up and it seems logical to match air to fuel ratios by mass . I'd like my next car to have some form of AFR meter so I'll see whats around then .

Cheers A .

Hey guys you have missed my point to his thread All I wanted to know would it be worth while intalling the haltuner to keep a check on a/f? I have no intention on tuning the car with it and it would be a shitload better than some a/f ratio guage from autometer or something shorly

[RB30-POWER]

These don't look to bad at all.

Im thinking of getting one shortly just to see what they are like.

Unless its accurate, I don't really see how you can keep an eye on anything, I mean a cheap narrow band will show if its gone way lean, or way rich, but chances are what really will happen is the AFR may drop from say 12.0:1 to 13.5:1. And this could be a big concern on a forced induction car. I just don't trust a narrow band to show me that small change instantly.

At the end of the day, if your car is tuned properly, and you don't tinker with it just keep an ear out for detonation.

If you want real accuracy get a wideband.

If you want something a little better then the standard narrow band get the Haltuner and included O2 sensor.

discopotato03, said he used one with great sucess, get one and give it a go. He has had real experience with it. Im just going of the specs and what i have read from users of the tool on other forums.

Let us know how it performs.

I hope we can keep adding to this discussion.

Cheers!

My answer would be yes but they have a new version soon to be released . They are getting a 5 wire Uego probe which will read between 10 and 20:1 AFR and could sell for around $300 (current estimate) . This is good news to me because the LED display should work with it once the narrow band eproms are exchanged for the wide band ones . EFI technology say the sticker on the front of the display is changed for one with numbers ie 10 11 etc up to 20:1 . Does anyone have any details or experience with the Uego 5 wire wide band oxygen sensor ?

Cheers A .

We use the Bosch LSU4.2 5-wire, wide-band O2 sensor. Cost is $US80 plus freight (no import duty, good on you Johnny, Feee Trade Agreement). Works perfectly with the Motec, Autronic and LM1 A/F ratio meters.

[discopotato03]

Thanks SK , did a search on the LM1 and found lots of information on the 6066 Bosch probe and some on the NTK version . I'll contact EFI Technology and see which one they're going to use .

Was yours imported from the land of George Dubya or are they available here ?

Thanks A .

whats the LM1 A/F Ratio Meter worth and where can you buy them as have been looking for a good a/f ratio meter for tuner for some time

has anyone run one of these ? if so how do they rate

[discopotato03]

Just off the tellingbone , EFI Technology will be using the Bosch LSU Version 4.2 wide band 5 wire oxygen sensor which they say should cost $140 by itself . Their next Haltuner version kit with the above probe should retail for $300-350 complete . I don't know if it will have a memory function or logging facility but may suit some for monitoring or diagnostics .

I haven't used one that had a numeric display , only the LED type but I suppose its the accuracy thats important . I gather most professional level equipment is numeric from what Ive seen .

I got mine from the US direct, we have a race team that we supply in Florida and they get stuff for us. Cost around $US370, plus $A30 freight. Innovate Motorsport have an Australian agent, it's on their website.
