Kyle you know how i feel about the Blow-thru.

your numbers are to low for something like that!

The blow thru is only for 600+hp

This is my theory, The maf is located way higher on the intercooler piping. Take into consideration your running a 3 inch.

The car isnt idleing high enough to get proper A/F mixture! because its not bringing in enough air.

By the time your maf see's air, to much fuel has been introduced!

Only thing that can solve this IMO is raising the idle to around 900rpm!

 

i dont think thats true

i was suggested to run the blow-thru on my setup and i was only making about 450whp. it helps tune the car's idle and get a more precise tune. think of it this way. the MAP sensor is located on the intake, the car reads the air at that point. the air has to travel a good distance prior to entering the motor on a FMIC setup. its about 6-8 feet total after the MAP sensor it has to go into the inlet pipe, to the turbo, through the pipe, through the intercooler, into the next pipe, up back through the engine bay, and then finally entering the throttle body. this is why the blow-thru setup is really effective on 375whp and up. the air is read at a more precise time, just prior to entering the throttle body. youll see alot of cars come stock with their MAP sensors right on or near the throttle body.

 

one downfall to most of the tuning programs is they have to be tuned via the MAP sensor. good thing like the Hydra system and the new AEM where the car can be tuned without it.

 

anyone wanna donate a hydra?

 

you need a sponsor, you are asking for all kinds of donations

 

haha i know! ahem anyone want to sponsor?

so i just got done reading a thread on nasioc about tuning blow thru with open ecu and they talked about the horrible idle and what they did to fix it... and all the people who have them even with simple setups say them love them once its tuned in correctly just that it takes a lot more time to get it good

 

ps anyone have the cable they would let me borrow so i can try seeing if i can fix this myself?

 

all kyles system only point to the MAF! rough idle, boggy around 2-3k

I think it has to do with the Blow-thru.

 

just buy the tactrix cable. its only $80. For the amount of time itll take to fix your problem, itll be worth it.

 

This is the 1st I have heard that there was an issue (and my phone has been the whole time). The car was running good when we stopped on Saturday when the huge lightning/rain rolled in.
