sorry

So the way i would calculate the ttp, fuel and time scalers would be the whatever change i did to the injector mutipler calclated in percentage? The ttp min does affected the top engine on idle so i left it stock The ttp max i set to 255 which control the max time the injectors and stay only The tim...

I think im falling flat on my face because my injectors are being pegged when i get into boost. Im going to drop in my 480cc injectors tomorrow. timing seems to be fine now. I just need extra fuel on top. I'm acutally pretty happy that my z is improving everyday. Thanks for the help guys.

I do have a silicone s-bend inlet which is only reinforced with exhaust tubing in the center. I'll try to change my set up to bypass that.

P.S. Am i suppose to make any changes to my wiring harness this thread speaks about it. http://z31performance.com/forum/viewtop ... f=6&t=7925

i have two sets of plugs i've once set gaped at .25 and the other at .40 I have not cleaned them while i was testing with them. Something i will try swaping tomorrow.

When i drive it accerates slower than normal until boost kicks and it drives alot better until 10 psi then it shuts off like if the engine was turned off. Im able to get it to run with a 800-700 injector mutiplier at 13.5 afr at 800rpms it runs jitterly but runs alot better at 10 afr on stock 260cc ...

i have readjusted my t-belt and didn't check the dizzy thanks for the input guys.

whenever i try to set the timing on the z at 800 rpms 20*almost seems to be maxed out in the clockwise direction. i dont remember it being this way on the stock ecu. what are some of the things that could cause this.

I found the problem......................... Apparently Nistune needs gasoline in gas tank to the pump to injectors. :lol: I decided to pull fuel line off to see if there was gas getting to the injectors it only split a few drops, when opened the fuel level sensor and took a look the tank had hardly...

Thz for the reply:roll: I think most here agree that working on cars its love hate relationship.

I only have the wide band (not connected to nistune). When i had the car running it was with the stock 260cc injectors and idle was perfect. Yesterday i installed my 480cc injectors the K value is 865 (moved it up and down) with the z32 afm. I played with the injector latency from 0 to 3000us with n...

My setup is 9:1 compression, 480cc injectors but im troubleshooting with stock 260cc, z32 afm,hx35 turbo and 87t ecu . Here what ive done so far. ADR: i set the "afm leg offset" to 0 since im using a z32 afm. i loaded the 87t bin and changed the afm from z31 to the z32 this changes my inje...
