Hi Everyone. I just got a Hondata Reflash for a close to stock RSX-S with Intake. I am considering saving up for type R cams or at least mroe aggresive cams or intake runners. Do I really need to upgrade the ECU program for $200. Would it cause problems with fuel/air ratio?

 

yes it is a smart thing to upgrade ecu, ur a/f ratio could be horrible lean. with k-pro they already have a base map ready for type-r cams, dont run reflash with anything other than what it was reflashed for... unless u want ur motor to blow! k-pro ftw

 

t-town_ep is right ... when you reflash your ecu ... your only making it adapt to pull max performance out of whats already in your engine bay ... what ever mods come after need to be programmed into your ecu ... if you are planning for more parts dont put in your cams just yet ... what till you have a group of parts to put in then re - TUNE your car no need to reflash ... most of the time you reflash if your only going to use an intake, headers, and exhaust and what to get the most out of it to do auto cross ... but if your planning to drag then your going to be using more hardcore performance parts that need to be fine tuned on a dyno more likely ... well thats my advise for now ... just put in parts in groups at a time to not spend money tuning and re tuning every part ... good luck

great post!

U will make more power with i/h/e k-pro instead of i/type r cams/reflash, wit k-pro u can tune all the parts u have to ur motor. Trust me u can never go wrong wit k-pro. I use to think k-pro was overrated until i bought one!

 

I would suggest K-pro. Not only because it comes with a base map for running the type R cams but it has room to grow along with your mods. You get somemore parts and the reflash is not going to change, K-Pro the sky is the limit.

 

i have heard some down falls for the k-pro ... but im not sure myself since i dont use either ... plus there are other types of tunning out there ... your right though ... k-pro = sky is the limit but same with other ecus it just depends on your tunning ... k-pro is just easier cause it has k series mapping on it hence the name k-pro, the k stands for k series, i mayself plan on using the hks fcon even though im not going turbo, but more simply because i like the performance outcomes from hks so far in not only the rsx but many other cars ...

 

id go with k-pro if your going to be seriously moding the engine and plan on spending money, if not itr cams and reflashing the ecu is fine.

k-pro is definelty easier to tune with, no cutting/splicing the wire n such, u can tune timing/ignition/cam angle/fuel basically anything with k-pro. i think that hks fcon is a piggy back so u will be limited when it comes to tunning

running itr cams with a reflash i not fine, his reflash was tuned only for an intake. running itr cams with that kinda reflash is dangerous

 

Well I think ill only keep an intake and possibly type r cams with an upgraded ECU reflash b/c i dont plan to do much else. I don't have the money for K-pro and dyno tuning+more parts. i/rh/itr cams/hondata reflash for itr cams will probably be my limit.

i was talking about reflashing for the itr cams.

 

i dont think you would be reflashing the ecu ... more like tuning it which would require either a basic street tune or a full dyno ... the cams are something i feel should be fine tunned for max performance not just bolted on and than reflashing the ecu for a base map including the cams but who am i to say what you should be doing with your ecu ...

 

reflashes are meant to be used with what the reflash is meant for, and nothing else. also, the base maps are Hondata's view on getting the most potential out of the mods for which said reflash is meant for

 

Get Kpro. You really should not mod a car without having the proper tools to tune it.
