Well i think i made a noob mistake. Since this engine is now turbo'd I have added 80 lb ford racing injectors... I had the accel enrichment adding up to 16ms of pulse width because thats what the stocker 24lb injectors were running. I did a quick fuel injector calcuator and it said at the MAX my ...

Ya I know I tried auto tuning it at idle with no load and that spot where it chokes out wont go away. I dont know if its a sensor malfunctioning or the tune itself. I kindof lost motivation when i couldnt get it to smooth out. I have had this runing before with this megasquirt and it was smooth. But ...

I have a megasquirt 2 assembled unit running my chevy 350 Tuned Port Injection. I have set it up for HEI. I have been trying to iron this problem out with no luck. It basically falls on its face when you press the gas quickly but if you slowly accelerate its fine. just quick pulses on the gas it ...

ya I'll check it tomorrow but its not running rich and getting super hot. I'm going to pull the fuel pump fuse and run it on starter fluid at the throttle body. if it runs smooth that will tell me on of the injectors or more are stuck closed. they are a brand new set of ford racing 80lb. I think ...

Well nothing fixed it. It does idle but still extremly unstable. I messed with everything. Engine however is getting up close to 200F and it never got that close because I have a 160 thermostat. I know its curculating but it seems like its running hot but the Fuel ratio is about 14-15 but thats off ...

I have corrected the table (newbie mistake) and I will try it again tomorrow. I have checked all the connections to megasquirt and everything checked out. I did change the spark dwell to 1.5 MS as suggested but a writeup on DIYAutoTune about TPI and megasquirt. Also I did have my ignition set to ...

Well bad news... after replacing the spark plugs with new ones gapped to 28-30 the problem with the engine still ongoing. I just put in a brand new distibuter and aeromotive Fuel pressure regulator today too. the phrase "alll for nothing" comes to mind... here is a updated data log of what its ...

Well pulled all the plugs today..... I think I found the problem. About 4 of the 8 NKG plugs are firing down inside the threaded part of the plug. All I see is little puffs of smoke that come out in perfect order when cranking the engine over. What the heck happened. There was alittle black stuff ...

Thanks! I have the trigger offset set to 11

I have my Base Timing set at 11 BTDC on the crank, I also have a spark table that goes up to 34* at 6000 rpm. Now for the stupid question, does megasquirt or tunerstudios add the base timing in the spark table or should i + or - the base timing to what the spark table shows. please let me know I was ...

my redline is 5500 but I'm going to be around 10 psi at that point. knock detection is crucial when boosting so will it detect fine under 5500?

Okay I need alittle expert advice. I have a 350 Chevy TPI going to be running 10 psi with my turbo. I have a few questions, I'm adding a Knock curciut to my MS2 PCB3 board and would like to see if anyone has any pictures or maybe even a video on doing this. I kindof get what to do by the instuctions ...

Ill give that a try tomorrow. I bought a new distributer online last night. I hope i didnt get it for nothin... oh well. Im going to remove the plugs and clean them. what would you suggest on plugs for my engine. I have a set of NGK Vpowers and I think I gapped themm at 30...let me know. Thanks for ...

Anyone help?

I was looking over Megalog view and I think there is a problem with the "trigger +-" its stuck at -3 and doesnt move. I read this website said the VR (variable Relucture) tells the megasquirt when to fired and it takes 2 readings for crank position. They suggested to get a trigger wheel but could ...

Fuel in upper plentium, freaking to much fuel. what is keeping those injectors open so long? can fouled plugs keep it running like this? Maybe I just fould the plugs while tuning but woulding the somewhat fix themselfs. They are NGK V powers and only about a year old. I checked the 1 cylinder and ...

Went out today and tried getting it going... well I took the wiring harness out from under the dash and checked everything, looks good. fuel pump leaks back very rapid but the regulator and injectors check out ok with the clamping hoses method of testing. Here is a data log with the ecu timing ...

Also, are the 80 lb/hr injectors low or high impedance?

What would you change it to please let me know and I'll try it. The are 12 ohms high Imp

Here is the msq. Some of the mods are on the comment. I have a FIRST (tpi) intake to. Please look over the msq if you can and let me know if theres anything that would cause this insane instant flooding.

Well now Im stumped! I changed out the ignition module inside the distributer with 2 different modules from the auto parts store and nothing changed, still flooded out bad and managed to keep it running but only with the gas pedal half way down. Everything went wrong instantly when I was driving ...
