Outstanding! All this I had you do with the ECU temp sensor was to eliminate it as a problem...what you've told me has done that. Make sure you clear the ECU codes.
Next on the list was to:
- Check the TSRM FP range (the FPR)
- Check that the FPR was not open to atmosphere (bad vac line...
"Global" - means you adjust across the entire ops range...on the Lex/550 the required FP is usually at the lower end of the TSRM ops range (23-30 psi) to keep you from running excessively rich at higher boost. You can adjust FP to where the Lex/550 combo will run fine with no piggyback (you'll...
Was the ECU temp sensor still unplugged when it didn't take as long to get a normal AFR?
If you read my post on the previous page, the CSI is only active when the starter is engaged. Unplugging it will make the motor harder to start, but will have no effect on AFR once the motor is running if...
I really hate to be the bearer of bad news, but unless you have a piggyback (like a SAFC) the ECU on the 7M is not able to be tuned. The piggyback has to remain wired to the ECU...it cannot be removed without the ECU going back to stock fuel maps.
If this is the same shop that told you an...
That would be a good call ;)
Might want to invest in a WB O2 in the near future. Do you have a AFPR and drilled the J tube out to handle the Walbro?
Another thing about the CT26 based turbos is the compressor housing is restrictive at higher boost. Much over 16 psi or so and all you're...
On the Lex/550 combo, 18 psi is about max before you hit fuel cut. Depending on OAT it occurs between 16 to 18 psi. Take the tune slow and work your way up...watch carefully for knock (detonation).
Do you have a wideband O2?
More so a synchro problem...worn most likely and a gear oil with friction modifiers in it will make it worse. Synchro's need some friction to function properly...worn + slippery oil = hard to get in gear. Thermal expansion will just magnify the situation.
Another thing to look at is the...
