I had my car tuned a couple months ago, I didn't had the chance to drive it after it was done because I had orders to be deployed. Anyway I was riding on it to day and it seems that 3rd, 4rd gear the rev limiter is at 6k but in 1st and 2nd I can go to 8k can this be fix is it the hondata? If feel like it hit rev limit it just stops any help will be appreciated!!!


Set up:
Some info on the engine:
D16Z6
bore .20 over wiseco pistons 8.8.1 should be a little bit lower with HG
GE block guard
Scat rods
comp cam, sprocket and springs
ARP headstuds and cosmetics headgasket
RC 550cc and hondata s100b with aem fpr
turbonetics turbo t3/t04e 57 trim 63 a/r
tial 35mm w/g
greddy typy s bov
RH exhaust manifold with drag intercooler
AVC-R boost controller
egt, boost, oil guage
bbk 255lph fuel pump
2.5 flared to 3"Dp 3" exhaust

 

sounds like it might be the boost cut.

 

Can it be set different per gear?

 

Something isn't right here. That dyno graph looks messed up, the power shouldn't be dropping off like that with your cam, maybe vtec isn't working? 450 horsepower and only 125 torque? Also your making that much power with 550cc injectors?

 

You are reading the graph wonrg it mad 259 whp and 225 torque

 

How much boost was that on?? I dont think you can make that much power safely on 550's. The injectors have to be maxed out or close to it.

 

Well I guess I made a mistake reading it. If you look at the bottom of the graph it says 256whp/225wtq. Still kinda confused on that one though.

Yeah there is something definitely wrong with that graph. I wonder why the numbers are wrong on there?? Anyway Something is definitely wrong with your tune for your power to be dropping off that early, unless the RPM numbers on the graph are screwed up as well.

 

The car made 259 whp and 225 torque at 16 psi. The way you read the graph is the left side numbers are for whp and the bottom line is for whp and the right side numbers are for torque and is the top line

Well that is weird. You usually dont see a graph set up like that. It is usually the horsepower is the top line and torque is on the bottom. Also usually the torque and horsepower numbers are the same on both sides of the graph so it is easier to read. Anyway is your AVC-R hooked up right??? What are the boost settings for each gear??? It is a gear related boost controller.

 

yes it's but its not set up yet, but that should not matter it should still go up to 7k or 8k

Have you talked to your tuner at all?? Soundls like either fuel or boost cut. Check back with your tuner.

 

I just got back from the desert yesterday, they still close till Monday I definatley give him a call. I just wanted to go in there with some idea what it may be wrong with the car, do you know if you can change boost cut for each gear?

 

on the dyno chart, the scaling is just different, no big deal, its harder to read yeah...

as far as it cutting out, give us more info, does a check light come on, does it just sputter, or buck, or cut out completely....

Well now that Mase showed up on the thread I will definitely stay out of it. All your questions just got answered

 

check light doesn't come on, it doesn sputter or buck, it just it feel like rev limit it just stops from going oover 6k I switch gears and keep on going but then it does it again!!!

 

how cold is it where you are driving the car at? sounds like it might be spiking and your hitting boost cut. if not, im guessing fouled plugs or spark plug wires.

 

Not really cold at at all 70's

 

Thanks to everybody who helped!!! I found that my boost duty was set to high and the boost was spiking higher THANKS AGAIN FOR EVERYBODYS HELP!!!!

 

Sounds like boost cut to me.

Call the shop that tuned it and ask them what boost cut is set at if you dont know already. Does it feel like you hit a brick wall when it happens? Like you hit the brakes?

Try turning the boost down a couple pounds and see if it still happens, if it doesnt, you know the problem
