Hello there everyone.

Im into my hondas and im a member of CRX-UK and i've always wanted to learn the 'black art' of tuning ECU's.

Im basically asking what is needed to tune mainly hondas and if anyone could give me a rough idea of what you do and what i will need.

this is whats in my head, and if anyone could correct me if im wrong it would be a massive help.

you have your ECU and you open it up and take out a chip (i dont know which one) and replace it with an 'emulator' which has a ribbon cable coming off it, you plug this into your laptop, this streams the information into whatever software you are using and you record what its doing and the AFR's (LM-1) and then you 'live map' it so your AFR's are good?

is any of this information i have collected valid?

thanks very much, I heard about this on MLR and thought i would come and pick your brains.

thanks in advance.

Ronnie.

thanks very much todd.

any other links and bits of information that anyone thinks could be of use to me would be fanstastic and i would really appreciate it.

is there more things consider when mapping a turbo car?

are VTEC's a pig to map?

will i melt my engine if im abit eager?

is there a universal tuning programme for most cars/applications?

where do you get the software, is it free?

standalone or socketed?

thank you VERY MUCH.

Ronnie.

Hi!
http://www.pgmfi.org/ is THE place to start with Honda mapping.
There are millions of options to tune Hondas. First, get to know which OBD version do you have. Basically, pre-91 are OBD0, 92-96 are OBD1 and 97+ are OBD2.

For OBD1: use a socketed P28, P30 or P72 ECU. You will need a datalog cable (Hulog from xenocron.com for example), rom emulator (Ostrich) and software. Crome is free/cheap, but is pain in the a** to work with, eCtune is much much better but is about $200.

For OBD0 there is a BRE (Ben's Rom Editor, check pgmfi.org for details).

As far as OBD2 goes, there are no cheap diy options. But it's possible to convert OBD2 car to run OBD1 ECU. Or you can use Hondata/AEM/etc.

Mapping OBD0 and OBD1 VTEC's isn't so hard. It's about the same as mapping any other car, but you have 2 sets of fuel and ignition maps - for VTEC and non-VTEC operation.

Yes, you can melt your engine, just as with any any engine mapping.

Start with reading pgmfi.org knowledge base and forums, it will take weeks to read all related info and to start understand something, but there's nothing impossible.
