Recommended Posts

First configeration i have delvoped and i would like someone to check over before i start tuning. I have attached infomation i was given when i brought the products

Mainly i would like to make sure my injectors and ignition setup is correct.

1000cc  bosch injectors

NZEFI High Energy Single Inductive Ignition Coil with Igniters x6

Rb25det neo engine

 

Also what do you guys reccomend for a wideband controller? innovative or AEM or another brand? My mate has the LC2 and has been through a few 4.9 sensors which is putting me off that brand.

For the Bosch 1000cc/min injectors, injector set up data for a Link G4+ ECU is as follows for a base (differential) fuel pressure of 3.0Bar with petrol:
Fuel system type - MAP referenced
Injector Rated Fuel Pressure - 300kPa
Injector Flow at Rated Pressure - 906cc/min

As for the wideband controllers:

I have a strong hatred for Innovate units, always having sensor failures and heater issues.

As much as I dislike just about all AEM products, I have not had any issues with their wideband controllers.

I do like the new Link CanLambda units a lot.

I have an Ecotrons CAN ALM on my own personal car and have had zero issues with it.

I will back up Brads comments here, avoid innovate.  AEM X-series seem to work well and have none of the innovate problems, they can be connected via analog or CAN.

Dont forget the Link CAN-lambda, it will give you a few extra functions over 3rd party devices such as better error handling and proper sensor warmup strategy.

I'll share some personal opinions from my own experience, take it as you will....

As mentioned already, I would also strongly caution anyone away from any Innovate wideband controllers...   horrible ground and signal noise issues, heating issues, sampling average and delay issues.

Have not had any issues with AEM controllers. Response time is great, and they have CanBus/OBD2 gauge controllers with 4.9 sensors finally.

Currently use a Ballenger AFR-500v2 with a 4.9 sensor in my daily, and has been reliable, with the added bonus of being upgradeable by ECM to an AFM1600... although they have their own "special" connecter on the 4.9 sensor, that you can only purchase from Ballenger, it is at least affordable.

If I could have easily sourced one locally in the U.S., I would have paid just a hair more for the Link CanLambda without hesitation....

With all that said, I would recommend finding a wideband controller that uses a Bosch LSU 4.9 sensor and preferably is CanBus based.

 

I'd also recommend finding more data on your injectors to characterize them properly

I cant seem to find the Ecotrons CAN ALM for sale in NZ, possibly only overseas? I had a look at the link CAN wideband and thinking that may be a good choice. Scary price though, guess you always get what you pay for though.
