Im about to install the mrev2 and 5/16 spacer on my 04 6mt non rev up coupe. My current mods are stillen td and injen cai and technosquare reflash. Does anyone know if i will need to reflash my ecu again?? I think i have the basic technosquare reflash. How can i tell if my car is running lean after i install the mrev2 and spacer. Thanks in advance!!

 

Well, you definately should have waited for the tune after these mods.

Not sure if you need to reflash your ecu though; Someone else should know the answer.

i think technosquare will reflash it again for only 150.

chances are, youll need to again.

 

I just got my car custom tuned by TS last week. You don't necessarily HAVE to get it tuned again. If I were you, I'd wait until I installed another performance mod (if you're planning on modding more), then get it tuned. And hero is right, it's 150 for your next tune.

 

thanks for the info guys. just installed the mrev2 and 5/16 spacer and it pulls harder now and sounds great. Doesnt seem to be running lean but what is a for sure way to tell? The only difference i can tell is i idle just a little lower now. Technosquare raised my idle to about 800 rpm. I think. but now i think it idles aroun 700 to 750. Any thoughts??

 

get a dyno with A/F meter to be safe, or you can install a wideband a/f guage in your car.

 

Did you ask Tony at MotorDyne about the Mrev2 with the '04 G? It is my
understanding it isn't needed with the '03/'04 models. The spacer will make
a major diffrence from idle to redline.

 

^^^He's right...The MREV2 is made only for the REV-UP motor...

 

I have an 03 and I'm thinking of getting either the 5/16 or 1/2 spacer and MREV, but according to hai109, the MREV isnt made for non revup?

 

tony once replied to me in a PM that the mrev2 MAY be used on a non-rev up motor, the gains wont be as significant as a rev-up motor though.....also it had a greater possibility of running lean but this varies by car..... the lower plenum (someone correct me if im wrong) is just the non-revup up plenum slightly modified no?

 

You can just get the spacer...There are older MREV kits that will work on your older model. I don't think Tony sells the older kits anymore...I could be wrong...
PM him and ask...He's a very nice guy. I met him at Autocrave...

do a search. mrev2 is for revup and nonrevup motors. On non revup you need a tune if u run spacer and mrev2.

 

you are 100% correct.

Tony made a thread with dyno's on the non-revups and revups with MREV2, MREV2 is compatible with both revup and non revup, it will have a bigger impact on revup's but will also make a significant improvement on a non revup if you get the A/F ratio tuned.
