Did that, no change.

Codes: 21,31,51 less than 1ohm measured between afm sensor and ecu on KS, VC, E2, THA and OX, HT, B+ between ox sensor and ECU. VC = 4.99V when IGN is on and 11.8V between HT and B+ when IGN is on.

New used afm installed. Identical symptoms. I will pull codes and try reseting to ign timing today again. Also will try my backup ecu. Help?

And I know a little about feed back based microcontroller based control systems. I am heavily leaning towards the lack of afm freq input being the problem. While the tccs is seeing the correct voltage on Ks it is not getting the input needed to adjust the injector pulse duration. Is that a...

Hey jet jock. I would be glad to provide you with any diagnostic information that would help but unfortunatly I am new to this and do not claim to be a professional. I have rag through wires and i have tried to follow along with the diagnostic procedure outlined in the tsrm. I did read thos...

Exhaust Not Plugged. It just has a 3" Divorced Down Pipe with no exhaust from there on. JetJock This thread is still alive because I am out of town working and have limited time to work on the truck when I am back. Add that to the fact the Supra parts are non existent in North Eastern Ontario...

Yes it is deleted I am not making boost at all, I cannot make it past 2700 rpm without hitting fuel cut. I severely doubt it is a boost leak or I would be running lean and I am running at 10afr

As soon as the SAFC was hooked up and it did not see any Frequency I disconnected it and reconnected the KS input to the ECU. So just to clarify... THE SAFC IS NOT ALTERING ANYTHING IT IS JUST OBSERVING RPM AND TPS.

OK. Just checked my TPS. IDL 0.5mm 0.987mm Measured@TPS 15ohm Inf Measured@ECU 44ohm Inf VTA Actuates between 0-5V as seen at the ECU Down Pipe is at the welders getting modified to clear my transfer case so cannot run engine.

I am about to do that tomorrow. I just got back to town (My work has had me out of town the last month) . Thanks for the Input! This has been my avatar as long as I have been on car forums. I saw is on a nissan 240 board and used it as my 7thgenhonda Avatar...

No Sadly I am not effeing with you. I had a Honda before this and I knew that sohc 1.7 was a lost cause for power so I focused on suspension tuning. Engine Tuning is a new game to me. It has been set with the motor off and the pump running. Experimenting with turning down my afpr didnt really...

So just turn down my AFPR?

I don't have the original Parts anymore. I pieced this motor together from a short block and shoehorned it into a pick up

Well I was trying to lean out my 10afr Idle. I thought the Rich condition was because of the 550's and Lex AFM. I thought that was the root cause, along with the walbro 255 and the -8 supply line. The fuel system is supplying too much fuel, and the stock ECU cannot correct it (IMO) How can I...

I got the SAFC Because 10AFR is very rich and my plugs are really black Ok so my charge piping is pretty simple. Turbo Hump Hose Coupler 180' Aluminum Bend 45' Silicone 90' Aluminum Bend Hump Hose Coupler My Accordion Hose is a brand new Ebay coupler. So I don't really have much to check...

So Boost leak is the General consensus? Even though my SAFC tells me there is no frequency coming from the AFM? I don't get an AFM code when I run it though. Very Weird. Maybe this SAFC is NFG?

Also it is running pig rich. 10afr at idle. Plugs are black and fouled. This is why i got an SAFC. To try and lean it out.

The SAFC is not Intercepting the KS signal at present. I just have it Monitoring Throttle, Rev and KS. Originally I had a 31 but when I pulled my EFI fuse it went away. I believe it was only there because I had installed the SAFC and intercepted the KS signal. I will check again tomorrow. I...

Ok So Lex AFM, 550cc INJ, Walbro 255lph Fuel is at 35psi. I Try to rev the car in neutral and at 2700rpm my wideband shows it leaning out in spikes and it wont rev higher. The ECU tests fine (5V on KS and VC when IGN on and 4V when running on KS). I Put my SAFC on it to see it it sees any...
