Tuning Results @ Hitman - Injection Tuning

[satanic]

Hey BUSTER I did see your car in there... I was jaw dropped - your gearbox system is what I'm going to be aiming for maybe

Umm the retard on the shift points? I'll leave that to the tuner I seriously would not know, will need to go and do some research!

[FATAZZ]

congrats on the tune,

a bottle of that Octane booster stuff and you could crack the 200rwkw mark.

This is the problem everyone is having with wiring over the top of the original computer as unless the haltech can take 3 inputs (which as far as I know it cant) and apply a igntion retard based on a torque calculation (maybe MAP input but would be shitty) then its going to wear your trans really quick.

I know the new autronic SM4 has WOT ignition cut but thats still not good enough as its the medium and light throttle driving that I think will contribute to the most wear. The problem is that all aftermarket ECU drive the coils directly which is where the problem is.

Now I'm not trying to plug the XEDE here but AFAIK it is the only piggyback apart from unichip that moves the crank reference in order to trick the ECU into think there is more or less timing. This way it still allows the standard PCM to still control ignition retard on gear shifts.

Your really at the level where you need fuel and timing control which the XEDE can do both as well as boost and water/methanol injector control. It will also account for larger injectors as well.

Octane booster I was told to never put in before a tune Reasons would be obvious I would've thought unless you owned a race car!

As for the XEDE, so you think it's a better system? The Haltech e11v2 sounds pretty damn powerful to me... but I'm open to all options, just that Hitman pushes Haltech

Its more of a case of the xede was designed as a piggyback while the haltech was designed to be a standalone ECU. In both situations you will have to piggy back either system. Its just that the haltech cant do the torque reductions on shift while the xede can.

Can you provide a link to this XEDE item?

Its developed at my work ChipTorque. We use it on the BA falcons, the entire subaru range, the entire mitsubishi range but mostly the EVO's in the states, lotus elise - in the states, porche -996TT, BMW - M3. We even used it on a turbo RX8 that we were contracted to tune by MAZDA Autralia. I tuned a 296rwkw 1jze soarer auto a couple of weeks ago. Its really just depends on the crank signal as to what we can put it on.

Cheers for that but you don't mention Nissans at all . . . is there a reason for that?

Haltech E11v2

7 Analogue and 4 digital inputs

EDIT: Ok I know it's an American site but the only Nissan they have is 350z - care to elaborate?

Thanks for clearing that up BU5TER

Haltech E11v2

7 Analogue and 4 digital inputs

Yes it has those inputs but what I was getting at is that you cant assign those inputs to a table and change the axis of the table and the fuction of table itself. Basically you cant configure the haltech to take in 4 shift solenoid inputs and assign a load/ignition retard table to each input.

My boss isn't sure that he wants to develop the xede much further. I however can see that it would work just need his go ahead. If I can drum up enough interest then it will go ahead. The thing with the nissan CAS is that they have a weird 6-5-4-3-2-1 crank signal thats is very unique. Which doesn't mean it couldn't be done. My cars is currently off the road which means I need a test car. It usually only takes a day to configure the xede for a car we have never seen before. In that day we scope the crank trigger and then get the computer engineers to configure the xede. All the other sensor will be easy as they are very generic in their operation.

PS: the 350z has a 36-1 crank trigger which is very common.

I went for the trip with Stan out to Hitman on Saturday.

Highly suprised at the a/f ratios on the inital run.. quite scary when you think about it. there was no noticable pinging or any wierd noises from the motor either while it was running like that... hmm

very happy with a solid power figure from a comparable dyno. the 200rwkw barrier could have been broken with a closed loop boost controller, as the hybrid boost controller at the moment is running in open loop, hence the boost drop off towards the higher rev range.

BU5TER your car is amazing. What an awesome combination in there The B&M looks right at home. Anywhere where we can see some details on your car?

[satanic]

rob82 - where abouts are you guys based? If you are 100% sure that this system works, I wouldn't mind lending my car to you as the guinea pig

Maybe we could work something out

[satanic]

One more question for everyone; the boost is currently set at 11psi - is 200rwkw an average figure for this boost level or something higher?

Do keep in mind I'm still running stock front/dump pipes + standard compliance cat Man I wish they'd hurry up on making those pipes for me... That would've pushed me into the 210rwkw mark for sure.

Still running the stock exhaust stan.. have to get that fixed than.. dyno day is coming up soon lol..

Edited February 27, 2006 by Links

[satanic]

It depends how fast these exhaust guys can get it done... it's a custom pipe that they're making up for me

The cat part is easy, just thought it'd be better to do it all at once ~

The xede looks like quite an interesting system..

http://www.xede.com.au/files/XEDE%20Tuning...%20Version).pdf

Main advantage you are going to get is that your ECU will handle the auto transmission, so this should be able to be used perfectly well I guess..

you can also adjust the timing easily enough..

On the site - says you can use it with an R33 skyline, what's the difference in signals from the R34 to the R33 going to be??

You can also control a boost solenoid as well stan which means you could possibly wire in the stock boost solenoid to control your wastegate..

Maybe an option.. depends on what deal + the support you can get, haven't seen the haltech one really, couldn't find as much info on their site..

any monkey with a laptop (and a some practical knowledge) could tune with the xede.. maybe talk to hitman and see if they would be able to use it.. and make sure he's 100%..

looks like a good option

just noticed.. Rob82 is in brisbane.. we're all in sydney..

The difference between a R33 and a R34 is that one auto is tiptronic with a complex shift logic while the other auto is your common auto gearbox.

I wouldn't say that there are different signals, just more signals coming from the R34.

I was also looking at the Bikirom option as well which is a ROM-tuning implemenatation - but I came to the conclusion that this is not the way to go as it'd mean I'd have to take it back each time I changed something. Not only that, I'd have to take it back to the same person!

I think you definately want flexibility on who can tune it for you.. worst thing is locking yourself into somewhere, knowing that if something goes wrong.. they are the only ones that can help you..

[satanic]

WERD to that one
