Hondata

Nothing wrong with the wastegate. It's hitting boost cut in first gear with no duty cycle but when turn off boost control all together boost stays steady 9.8 psi. It's something to do with boost by gear
When using fixed duty it holds 14 psi every gear perfectly

Hondata S300 V2 Serial Number - 22000
1999 Honda Civic SI
OBD1 P28 ECU
Everything electronic wise in the car is bone stock, just an obd2 to obd1 boomslang jumper harness to run obd1.

When using boost control as fixed duty cycle setting. it works perfectly fine. we added 50% duty and got out 14 psi ...

Ok this started happening out of the blue in my car. I had been running gear based target psi for years no issues. thougvh my solenoid was bad changed it out and same problem. When tuning and running fixed duty cycle everything works properly. when switch to gear based it just spikes right to boost ...

Thanks for the info on the oil pressure now just have to figure out oil temp

If your reving the engine to an rpm point that you would normally have vtec engaged then it's fine. Put the vtec mph to 0 and it will engage burning your burnout and makes a hell of a difference in power from my experience.

Hey guys im stumped. I want to get an oil temp and oil pressure sensor and wire them to my hondata s300 for logging and also to display on my tunerview. I picked up an autometer ful sweep temp sensor but its a resitance style sensor so i m unable to use this with the hondata. i need a voltage style ...

Well i do agree on the wiring diagram cause for people that arent sure the help file in the s300 software for FANC tells your nothgni more than FANC is fanc ontrol LOL. it shoudl tell you how to hook it up and how to set the perameters etc.. but i figured it out for my self browsing the software

IDK but go to the help menu in the s300 software type in fanc. then click vtec perameters and it will show you there are 6 outputs on the ecu that are wired to a relay turning the relay on and off but the relay gets power from the battery and thats only for the vtec solinoid which doesnt draw 25-30 ...

The valve lash as in clearence adjustment? for crowers its .007 on intake and .008 exhaust on a cold motor. IMO get rid of the crowers and get JG303 cams from jgengine dynamics. best LS cam ive run a few crowers and the jg303's. the jg's kick azz. and pull to like 8600

I dont run an LS anymore other than a crank & final drive & 5th gear . I used to be big into the LS scene but went to the dark said of vtec LOL. I was running a gt35/t67 though at one point in a hatch with a build LS.

Get your self a pressure transducer, autometer part number 2246 and wire number 5227. the sender should come with the specs you will need to input into the software. then go to the settings menu in the s300. use analog input 1 or 2. if your using 1 you have to install a 0.1uf capacitor into c42 if ...

Ive trried to use closed loop a few times and was always very unsuccesful so i stoppe bothering. LOL good luck with it

Not that this fixes your closed loop probelm but i have always run my cars open loop and any car ive tuned. i never put them back into closed loop and never had an issue. if its tuned properly it shouldnt need anythign more than intake temp corrections adjustment as the weather changes.
