This is what the DIY coolant reroute looks like at the front of the engine. I'm going to have to cook something better up when intercooler pipes get involved.

Nuts. I missed a connector that I needed to swap. I kept the 1.8 TB, so the IAC still needs a connector on the harness side.

I ordered the FM 1.8 swap kit, but I deleted the 1.6 TB adapter because I wanted to keep the 1.8 TB. The throttle cable left a bunch of slack even with the cable adapter because there is no TB adapter in between the IM and TB. I had to make an extension plate.

****EDIT******

I had my wires crossed. switch the red & grn wires.



I'm intending to run the car using the OEM 1.8 variable TPS. I rewired the 1.8 TPS using the 1.6 wires as pictured. I hope this works...

I only ran the stock injectors on the 1.6. But you're saying I could roll over my old tune with changes to the req fuel, and the injectors? I'll also need to update the sensor calibrations.

I gotta improve the cold start. Man, it sucks. I also need to sort out the acceleration enrichment. I'll post some of my butt map/logs after I start up the new motor.

This looks right for the IAC connector! Hard to find on the forums, as most people retain the 1.6 TB & IAC.

The above connector is the correct fit, but the OEM pins are slightly wrong. Since I didn't have the correct pins on hand, I modified the OEM pins. Here are the mods I made to make the pins seat & lock. In each pic below, I've completed one pin in the step described so you can compare before & after:



Squish in the side tabs so they are flush



File the tags flush on the nose



Hog out the locking detent so it extends about 1/16" closer to the nose.

This all took about 5 minutes. Not as clean as using the correct pins, but it gets the job done. If I had to do it again, I'd just buy the connector with the pigtail already included.

Had to do a bit of a reroute of the coolant...reroute. I had the hose drooping low, and there was no way I could burp the line. Here's the new routing. I spliced in the OEM 1.6 radiator hose.

I'm sorting out my map for the FF610 injectors I ordered in February. Based on the recommendations from this thread, I'm running the following:

dead time = 1.179ms@13.2v
battery correction = .144v/ms

I've multiplied my static flow published on the cards I received with the injectors by 1.04. Here are the injector serial numbers, published flow, and corrected flow

serial # published corrected
f6ak43 609cc 633.36cc
f6ak49 614cc 638.56cc
f6ak55 609cc 633.36cc
f6ak62 610cc 634.40cc

the average corrected flow is 634.92cc. I input 634cc into tunerstudio.

does this seem sane?

Did you do your coolant reroute with the motor in the car or before?

I did it with the engine out. I had tried running the hose lower down closer to the alternator. With that big dip in the hose, you get a big air pocket it the line that will never come out.

Changing injector dead time from 1.179ms to 1.124ms due to silly math error I made last night.

Everything is buttoned up, and I'm calibrating my tune. I've got the TPS wiring fixed & the TPS is calibrated now. The only things left to do are to tweak the Hz rate for the IAC, test my injector & spark sequencing, & fire it up! I should have enough time in the next couple days to get it running...

Car started right up first crank. Only tuned the idle cells, because I couldn't get the clutch to operate. Hopefully there's just air trapped...

Had to move the idle VE up about 25% from 57 to 72.

Fiddled with the clutch pedal, and got it to engage. I've auto tuned up to about 3k. Gotta chase down a noisy exhaust leak somewhere.

I'm having to add a lot of fuel to my VE table.

Checked your required fuel is close? I hate chasing down exhaust leaks. Glad you are getting somewhere

Exhaust leak fixed. Drove the car to work today. Auto tuning. Need to adjust the sway bar end links.

Ugh. 4 days on the road, and I have two symptoms: low voltage, and the thermostat gasket for the OEM thermostat neck block of is weeping.

I guess I'll pull the alternator & get it tested. Sure hope I'm not hunting grounding demons...

wackbards

iTrader: (2)

OK, so the alternator ground post nut had walked loose. Easy fix there. Cranked on the coolant neck cap, but my gut says it's a crap gasket.

Trickle charging the PC680 battery back up. It was reading at 11 volts by the time I got home.

If that was more than an hour your battery is toast. That or your charge is toast.
