i have a 88 integra ecu right now will a pr4 make it any faster

 

the 88 should be fine, i heard the 89 is better in a way...i can not confirm this, did anyone hear about this either...

 

pr4 is for a 1.8 liter lets think about that and the pm7 is for a 1.6 do the math some say the pr4 will make it faster but ur gonna be running rich also and possibly pay money for somehting u dont need

 

get a Mugen pm7 no govener for top speed so it will be faster higher red-line, and different fuel mapping. best bang for you buck IMHO

 

the thing is i already have both the 88 teg and the pr4 ecu, i wanna know if it IS safe to use the pr4

 

the PR4 is going to add a lot more fuel but yes this will work fine. My first motor swap after toasting the stock motor was a D15B8 L3 tranny and a PR4 ecu. emissions was a joke and i got around 20 mpg. but it ran fine. if you are looking to run lots of bolt ons and maybe some biger cams in a ZC the PR4 may do you some good.

 

use 88 teg ecu

pr4 is for a 1.8

too much fuel and if u need that much fuel get the 88 teg ecu chipped

 

PR4 Will not work.

 

well i just switched over to the pr4, ive been running the pm7 for like 8 months now, it does feel like it gets better gas in lower rpm, but the rev limiter kicks in at 7 rather than 7200 like the pm7, i dunno, but i dont know why you said it wouldnt work, it is fine.
