There was a Mobil dyno at the track Sunday and here are my results. Stock Exhaust except for Test pipe. Custom unfinished intake you can see somewhere here on the forums. a little Lean??

 

your picture doesn't work

 

only helps us if we have an account to login and see the picture... or you could attach it here.

 

I attached it here sry for the confusion.

 

look at all the torque loss from being so lean before 5.5K.

 

someone needs engine management

 

That looks about right. My effectively stock '90 made 105 on a Dynojet a couple years ago.

 

I was thinking about cheeping out there and going with an adjustable fuel pressure regulator. I'm planning on finishing the intake and doing a full exhaust and that's it on the engine. not really worth the hassle doing much more on a 1.6.

 

The ECU is the groundwork for all other mods though. Putting in a 1.8? an ECU would help. Turbo? ECU's is almost required. <shudder> supercharger? ECU.

 

EMS will give you more gains than a I/E

 

Humm, ok the next question is with the AFR's the way they are is it safe for me to keep tracking the car while i save my pennies or no?

 

afpr won't do anything if your ecu is pulling fuel there by decreasing ipw

you need an ecu like I said.

is it ok to drive as is? probably. after all its a dinky n/a 1.6. is it safe or efficient? probably not

 

You can tune the AFRs slightly by spinning the AFM around in the tube and dynoing at different angles. Gravity tuning lol.

 

It's still pointless in closed loop. ECU is always going to target 14.7 until about 5K, then it just goes rich.

I'd assume you could see 100rwtq from 2.5K to 5K by just adding fuel alone.

 

do NB's do that too? I know they get stupid rich up top, but didn't know when the switch was

 

Ok i am going to get a MegaSquirt, but i need to wait a month not because i cant afford it but i have not driven the car on the track in 3 months. Can i run the car on the track the way it is?? for 2 weekends?? before i have it down again?

 

yeah you're fine.

that's a very typical AFR curve.

I'm trying to remember where I saw a good before/after dyno from a MS. Maybe from diyautotune...

 

ah ha!

 

yeh i have been looking around
