im currently putting some rs pistons in my b20b im leaving the stock bore and so on, a b16 head with, blox manifold, skunk2 70mm tb, aem intake, dc headers, 2 1/2 mandrel bent pipping, as for that everything else is stock, im running a chipped p28, now my questing regarding all this, is after its reassembled, i planed on a dyno and tune but as i said im not using a hondata so a friend of mine mentioned to go to the person im dynoing @ and just get a chrome chip that has similar parts to what im using instead of getting it dynoed since it cant be tuned without a hondata and wasting money is that true ? can i just purchase a chrome chip instead and not have any fuel-air ratios to worry about i plan on taking it to the stip every here n there and its also a daily driver i dont wana worry about my car blowing help plz

 

your friend may be in the lines of the mentally handicapped. (or uneducated)
a crome chip can be tuned, hondata is not the only one that has that ability. In fact any of the honda ECU programs can be tuned, that's the whole point of them.
(Neptune, eCtune, Crome, even Uberdata)

B20 VTEC you will need tuning, crossing your fingers with a basemap is like going bareback with a hooker, you may be fine but there's some serious consequences that you don't want to think about.
The only good thing you friend said... talk to your tuner and find out what they prefer to use as far as tuning software. If they prefer hondata and you are not looking to drop the large amount of cash required. Find another tuner who's willing to work with another program.

One other side note, there has been an alarming amount of dyno plots posted in the last 6months or so that show previous Crome tunes vs current eCtune or Neptune tunes. All have significant power improvements in them.
I've made a lot of software jumps over the years. (hondata, Uberdata, Crome, eCtune, Neptune and a few others) I can tell you, currently there are drivability issues with Crome. Not major but they can be annoying for a daily driver.
eCtune and Neptune are the best on the block for the money right now. Hondata works well but over priced in my opinion.

 

if u build it , u dyno it.
Ur friend is not going to pay for ur motor when it blows cause u got the wrong chip.

 

If you're going to build the motor, tuning is a cheap investment to make it last and will be a cheap way to pick up more power. Hondata S300 is down to $450 new, S200 is like $200, a Moates Ostrich is about $170 new and is probably the best. I have a used one if you'd be interested, and the parts to chip the ECU if you need it.

 

ohh i see then where the hell did he get that from lol well thanx alot fot the input

 

S300 or Neptune! Crome is a poor mans joke.
