Hey all, sorry to sound like a newb here, but I have only had my prelude for a few weeks!
I am looking at getting a chip/ecu to upgrade my power and tq. Which do you guys reckon is the best to use?!?!
A mate has suggested Hondata, but their website is a little vague, and I am having trouble following. I don't know which 'stage' to go for.
I have a '92 Si Non-VTEC (H23 I think) NA, and I think that I can get a stage 2, but again I'm just not sure!
I really have no idea about this p28 p14 stuff, but I would love to learn!! if anyone feels like filling me in or at least pointing me in the direction of a website that can help I am all ears!!!

Thanks for your help!!

 

Hondata is the only real option for you, unless someone near you has techtom tools.

For Hondata Stage 2 you need a stage 4 user to help you tune or a hondata dealer. Stage 4 you can do the tuning yourself, it's really up to you how much flexibility you want.

For Hondata Stage 2, you need to do an ECU swap, the P74 and P75 are ECUs from the Intergra LS (B18B), and plug right in. Then the Hondata Stage 2 box can be added. You may want them to add the secondary intake runner control, or you will lose some low end power (H23 has them, but the Teg LS ECU can't run them without adding it).

Pthis and Pthat are the codes for the ECU.

 

Ahh, finally some answers!! Thanks for that, it sheds a bit of light on the subject for me!
