About two or three weeks ago, I got my car dynoed and I was pushing 155whp... The shop said that there could be a 15 percent difference in it, so I'm not sure if I either have 178whp (with the 15 percent) or 155whp (without the 15 percent). But anyways, that's not what I was talking about. For a JRSC GSR, I know that isn't much at all. During the dyno, my car had horrible air/fuel ratio's all the way around.. Running too lean and running too rich. The guy said I needed a new ECU to fix my horrible air/fuel problem and he said I could get at least 40hp more with proper tuning. I'm running a stock OBD I GSR ECU. I've been thinking about getting a new ecu, but I can't make up my mind... Which would be better for my set up? Hondata s300? Greddy E-manage Ultimate? Any help would be appreciated. Thanks.

jr tends to use the hondata units for their superchargers, but since you probably are like me and clueless on how to tune the ecu and/or have no means of tuning it yourself make sure your shop has the abilities and the certifications to tune your new ecu. thats about the only advice i can give. good luck!

Look into crome or uberdata... both are nice programs and are free.

I would go with whatever the shop knows how to tune with.

There's more of that if you LOOK BEFORE YOU ASK. Take time to learn and do it right the first time.

Go with a reputable tuner and find out what they like to use. Someone who lets you dyno while your A/F is all over the place isnt a tuner...

Personally, my preference is with Crome. Well supported now by its users & creator, new features all the time and they are constantly figuring out new stuff. Hondata S100/200 is limited in comparison to Crome now and the S300 is still pretty new and there have been a lot of good & bad stuff said about it so...

You could just get that P72 chipped and have your choice between Crome, Uberdata, Hondata or even Neptune

I believe that sh*t is also on the front page now...

Read UP!

Your ECU (OBD-1) can be modded to accomedate a tuning program like Hondata, or cheaper but just as good Chrome, Uberdata, Neptune, etc... Talk to your tuner also... you do not need a new ECU.
