XS Chip for GSR? Anyone tried it before?
does anyone have the XS chip on their GSR or has had it? here are the specs:
P72 : 94-5 Integra GSR (B18C1)
XS program
VTEC: 4400rpm
Rev limit: 8700rpm
This is designed for the dual stage intake.
its relatively cheap.. about 80cdn.. is it worth it to give it a shot?
Thanks

unless u have cams and valvetrain u wont want/need to rev that high

can you just drop in new cams and then run the chip?
i thought u would need to higher your compression or something...
And reving that high wont hurt the over all motor?

well, vtec does kick in at 4400rpm stock correct me if i'm wrong, along with the limit.. i'm not too concerned about it, i won't be revving it that high, i'm just interested in the new air/fuel curves.. will it be even beneficial with i/h/e?
thanks
thanks

Nope, generic one-size-fits-all chips have poor results at best.
Essentially they are the programers "best guess" at what A/F ratios would work for thousands of engines. Every engine from the factory is going to perform differently, and every engine is going to respond to mods differently. Because of this, each engine needs to be tuned specificly to get good results.

The first reason is that on most naturally aspirated engines operating
on pump fuel, the only way to achieve tangible power gains is by
increasing airflow through the engine. Chips cannot do this therefore they cannot make much difference in power output. Chip re-programmers can richen the mixture slightly at full throttle and advance the ignition timing slightly perhaps but this would be at the expense of lowering the factory safety factors for detonation and emissions. The absolute maximum gain in this instance would be on the order of 5% and could be as little as 0%. Most independent tests that I have seen on performance chips for naturally aspirated engines have indeed shown minimal or no gains in acceleration.
Some were slower than the factory chip.
Chips for use in factory stock turbocharged applications can increase
power substantially in some cases by raising the boost pressure. This
again reduces the factory detonation limits and you risk engine damage.
Without increasing fuel octane, you are asking for trouble especially if your engine does not have a knock sensor.
