What ECU is needed for a LS turbo

 

If you have to ask this question. I would suggest that you get one that you pay to have a professional tuner work on for you.

Do you have a local shop in mind to tune your car or are you going to try and do this all on your own?

I would suggest that you call a local tuner shop and ask them what ECU/EMS you require. At the same time you could ask them about boost setups and get a quote on how much it will cost to have it tuned.

To use a Hondata system, you will need to use a compatible OBD1 ecu from the list at http://www.hondata.com/ecus.html. You can then use the Hondata s100 or s300 depending on what options you want (http://www.hondata.com/sproducts.html). I would recommend the s300.

 

People still use Hondata? I thought that went out with Uberdata......lol

 

what do they use now?

 

i am. and i have done that already. i just wasnt too sure. i dont want to buy the wrong part.

 

i was told that vtec ecus with s300 do work with turbo ls setup and some no, they don't. what is the right answer?

 

The answer is yes, you can use an obd1 vtec hondata s300 ecu to run a non-vtec turbo ls setup.

A vtec ecu is the same thing as a non-vtec ecu minus the vtec components.

 

Neptune Demon... You can use ether VTEC or Non VTEC chipped OBD1 ECUs for a Non VTEC boosted build. The circuit is usually just turned off in the tuning!

Just an FYI, Some Non VTEC ECUs can be physically modified to run a VTEC build as well.

IMO going with a VTEC ECU is a better choice with most builds. It gives you the ability for future growth as well as the VTEC circuit doesn't necessarily have to be used to control VTEC components. They can be used for alternate inputs/outputs as well.
