Some time down the road I'm going to invest in one of these systems and I was wondering if anyone had any imput about either of them. At first I was quite decided about the Tec3 but just recently I have seen that Hondata now has a G-Force monitor with dataloging and I also noticed that the Hondata is a lot cheaper then I originally thought.

I know of local tuning shops for each system so getting the system tuned will be no problem either way. I know Tech3 is more advanced then the Hondata but it costs about 3 times as much.

Opinions of each system woud be greatly appreciated. Thanks.

 

What type of engine work is done to your car?

Do you need the ability to tune the car yourself, or are you going to pay someone to do it for you?

 

The engine is bone stock except for the i/h/e and soon to be custom intake manifold and throttle body.

I don't need the ability to tune the car myself and I would rather have someone who knows engine tuning better then myself do it.

The problem with Hondata is that I would have to buy a P72 ECU and jumper harness to just consider using the system.

 

What about buying the P72, the jumper harness and getting the ECU socketed.

Then, just take your car to a Hondata tuner, have them throw their setup in your car, tune it, burn a chip and hand it to you. Plug it in and go.

There's no need to actually buy a hondata unless you specifically need the special features that each level provides.

 

One of the biggest features I'm, looking for is data logging so I can compare what I did different from run to run.

 

interesting that you post this.....i've just been looking over the two myself.....although i'm leaning more towards the TecIII for when i take the 'boost' plunge and run SM....but that's not until after next season. i did notice that all but one of the CSP CRX's and most of the Miata's were sportin' TecIII's...seems to be universally popular.

while i was still at MU we ran an electromotive on our formula car....light years better than the shitty haltech's we were running on all our previous cars.

 

hondata triggers from the camshaft - Elctromotive triggers from the crank. Before I switched to Electromotive, I saw timing variations of plus or minus two degrees which meant I had to pull out timing to be safe...not good in my opinion. This is for a full race application where I am trying to get everything out of my motors - so I was able to look past the cost. For a street/track car I would use the Hondata purely because of the cost.

I was going to say I know of more cars running Tec3 then Hondata but that's isn't a fair comparason because you can fit any vehicle with Tec3.

One thing someone pointed out to me was that the Hondata runs through the stock ecu hardware where as the Tec3 is made of better/faster hardware.

 

.....I swear I've heard that before

 

Yea... I wonder where.

 

I went through a similar exercise recently. I was going to get the Hondata, but opted for the AEM EMS and converted my CRX to OBD I to use it.

I am very happy with the choice now, no chip burning when I want to change the tune. The worst part was trying to find the P72 in the first place, what a pain. Those things may as well be made of gold the prices they sell for.

The AEM has full datalogging, which is nice with the wideband O2 sensor, and has many inputs left open in which other things can be added. Maybe even a g meter?

No personal exp here but.... I have gathered that the hondata is for people trying to save money. I like the AEM and Tec III.

 

not trying to hijack the thread....but is the P72 the OBDI ECU from pre 95 integra's? what ECU would I have in my 94 RS.....isn't the code on the case of the ECU? I should probably just go outside and pull my carpet back and check for myself

 

Something to consider is what you want to do it your car. IT rules state, I believe, that you can alter/chip your ecu, but it must fit in the stock case. A Hondata system will do that. Some others will not.

 

The car is strictly Solo2. If I were to do a IT car it would be something like a 1st gen CRX

 

Why use a p72 ecu... why not a cheaper p28 or p61?.. That's what I use in my ITR.

Honda also has the neat ability to retain all the factory sensors and error codes, so you can see whats going on ... if something goes wrong.

 

The reason the P72 or P61 or P30 are better than the P28 or others is that they retain the knock sensor. I do realize that some people don't want them, but I for one do want it. I haven't seen cheap P61's.

Error codes are nice to have, I have not missed them yet (fingers crossed), but the datalogging shows all the sensors and what they are doing, so you can see exactly what they were doing when it is running bad.

Yeah I know.. I just figured I'd throw it out there for discussion ... I tinker w/ a stg2 for my lapping car ... and a 4b for the toy. so far so good... now I just need to get the system to play w/ 72lb injectors
