im having a slight problem with my fd , when im going a steady speed like 70 or so .....it boggs, like it had a bad fuel filter but im not sure if its it or not , when im going on a steady speed, it boggs and the regains it speed and it continues to do that .... and when im riding on 1-4 gear , it sometimes do that too...when i try to give it gas ...it just still boggs and pull, boggs and pull, then regains it speed when i step on the clutch and give it more gas ......., if someone knows the problem , help me out ...thanks

what ecu are u running? you'll need an upgrade ecu if you got all of those mods.

 

what ecu do i need?? data ?? could it be a bad fuel filter???

 

damn, all those mods and no ecu? get one asap

 

thanks for the advice .... but which ecu will i actually need and what brand is the best ...let me know

 

i have heard that the power fc is a great one. pretty easy to use from what i have heard aswell. you can check it out at rx7store.net

 

get a pfc asap. How many miles on your engine? I wouldn't drive it till you get the ecu installed, and tuned. You'll blow your engine otherwise...

 

the motor had 63k on it .... well i searched for a pfc and the price is way out of my range rite now .... what would be a little cheaper or any other brands thats out there that will work ....

 

There is nothing wrong with running those mods on the stock ecu. You should have a boost controller though, to control boost to 10 psi.

What is your boost pattern during this bogging event?

 

i have a hks evc and hks fcon which is not hooked up yet .... im actually running stock boost rite now ... and when it happens , its below 0 psi , it happens when im on cruise ...and when im starting off on 1st or 2nd gear ... up to 3 thousand rpm

 

sometimes it runs normal ......and somtimes it acts up

 

Sounds like it's most likely an ignition problem. Maybe a bad coil pack that cuts in and out.

 

How many miles do your spark plugs have on them? Or even your plug wires?

 

just replaced ngk plugs about 1k miles , and ngk wires about 5k miles

 

Check and replace the ground wires and add few more to the motor and transmision, it does help alot.

 

Good, Then nevermind.

 

I stand corrected then... I figured with all those mods, plus having a ported motor and all other mods, he had to have been running in excess of stock boost. But he seems to say that he is at stock boost... weird.

Rynberg knows best...I'd listen to him and make sure your boost is at stock level!

 

Well in your mod list it says "port motor". Is the motor streetported?? Although the rest of the mods would be fine on the stock ECU, im not too sure about the port work. If the motor is streetported the stock ecu cant change the timing to compensate for the larger porting and you should get a standalone ECU and a good tune as soon as possible.

 

yea its street port ..... got done be zmotorsports in houston which i dont recomend to go...mostly got dicked by he worked on the motor, apex 3mm seals and ported the motor..... so the best is to get a standalone ecu ??
