The ecu is e5 or e8?

 

Ecu is still the 5. They both are flash rom so makes no difference. Problem is the fuel mainly. I dont have access to 98 so have to run 95. Other issue is compression. New build and needs to be low compression to accept any ignition advance or horse power gains near on impossible. Is 220kw at the wheels so not to bad considering factory is just over 170kw at the wheels. Just gutted turbo upgrade turned into a down grade really.

 

Wouldn't mind seeing some logs. I'm making 245kw on factory turbo @ only 19psi on 98 and there is more in the tune at that boost and can run higher boost if I wanted.

I never liked a TD05/06 hybrid I ran years ago on one of my older cars, it was probably better on the factory turbo.

 

could it be the actuator? vaccum leak? or must be something wrong with the turbo. NZ EFI has a very good reputation in NZ.

 

Yes they said I could get another 30kw if run on 98. I need to run 95 as not close to bp. Eventually I will get G4 computer and set up two maps. One for 95 and one for 98.

 

NZ EFI are the ones giving me all info. They are convinced there was nothing wrong with the TD06, it just didnt work with my application but may have worked if running 98 octane. We are going to put after market plenum on, hone throttle body and put two external waste gates on soon, see how that goes. Further down the track im goin to do the cams and gears and put a link G4 in and have two maps, one for the 95 and one for the 98. Should be a couple of interesting projects and good to see how motor responds in the different scenerios.

Full credit to NZ EFI. They are getting me to where I want to be. I just didnt do my home work before spending money in the wrong places

 

Waste of time getting a G4, the factory ecu is fine unless you don't know what you're doing with it.

 

NZ EFi would be installing it and it would be dyno tuned using the G4. It would give me the ability to have two settings. One for running on 95 and one for running on 98 octane. Also options for electronic boost etc

 

again, factory ecu can do all of that.

is NZ EFi selling you on the G4 or is this another case of:

 

The factory ecu can do all that, no need for a G4. I have map switching, run one map for high boost and one for low boost, but could be used for different fuels etc. I'm also running ecu controlled boost. In a few weeks I'll be changing over to speed density to get rid of the MAF. You can even do launch control, flat shifting etc. About the only thing you can't do is run true anti-lag on the factory ecu. The factory ecu has come along way, check out geekmapped.com.

 

Thanks for the advise. Nice to know some one is helping on this issue as $2000 seems like allot to spend if not needed. How do you control your map switching and adjust boost via ecu?? very interested in your knowledge. Care to explain more about speed density as well?? Im at a cross road at the moment as to where to spend money to get got power gains.

 

Granted. Have sort of been swayed that way by NZ EFi but dont really know enough people to be told otherwise, hense joining this site. Give me some ideas as to where I should head with this thing as your advise would obviously be beneficial

That thread has all the info and has the rom and xml you need, but retain your maf. Buy an Openport 2.0 cable, get a laptop, a wideband and you are away. The map switching is just a matter of adding a pin into the ecu plug and having a switch with an earth. Switch open is one map, switch closed earths the ecu pin and it switches to the other map. Ecu controlled boost is all done by the ecu, just need a Grimmspeed 3 port to wire in to replace the factory boost controller.

There is also a thread on geekmapped which has a newly released rom that can do Speed Density. Again, add a pin to the ecu plug and wire in a MAP sensor and then change the MAF plug and wire in an IAT sensor. With my set up, I'd be able to switch between SD and MAF within a few minutes if I wanted.

Changing to an aftermarket ecu is old school thinking. There are some smart guys out there who have modded the factory ecu to do pretty much everything an aftermarket has, but still retains all the benefits a factory ecu gives you.

Get on geekmapped and do plenty of reading, plus evom has alot of great info if you want to start looking at tuning yourself.

 

Well put
