Modified the stock runners instead - the custom required too many angle alignments at the same time to fit - I found that the runner / plenum flanges are also offset in two planes.



55mm on center per pair, 135mm between pairs.


Honda fuel rail will need three out of four ports drilled. Going to weld an AN06 bung for the fuel line. Using 98 V70 FPR in pod - so only regulated pressure to rail, and return safer/simplified as a result.

Finally have the engine back in the car & starting to setup the fuel system



Fuel delivery uses '98 V70 FPR & modified lines, Quick release fittings.




Still hoping someone knows whether the map table values should be lowered or raised to lean out the map. EDIT: Regarding Map adjustments, I re-read the thread on ECUProject - lowering the table values increases fuel.

544 (2.3L) table:



Saab 514 (2.0L) table:



Values are lower (for the most part) in the 514 bin, I just don't understand this guys logic where he talks about % changes (in his for turbo enrichment)

ANyone have any experience at all with these maps? Any similarity to 2.4 tables?

Went with 16% higher values to lean out the table.

Setting up the LH (Saab MAF) intake piping





Saab 514 ECU



I had mis-wired the switched feed to the ECU/system relay, once I corrected that, the motor fired up instantly. Have to fit the exhaust to the header before I can run it to warm & make adjustments.

Couldn't get it to run right with the Saab ECU/MAF. Switched them out for the Volvo 544 ECU & 007 MAF, and it's much happier. I had to lean out the MAF adjustment significantly to get the AFR's in the 14.5-15.2 range at idle. Having trouble with low idle vacuum issues that don't help.

EDIT: Problem with Saab MAF is that it's LHII (LIKE '83 240), not 2.2, so the wiring to the MAF is different. I toasted the first MAF as a result. I added a pigtail for the LHII MAF & was able to run the engine off the Saab ECU/MAF.

Running well with the 554 ECU & 007 MAF. Had to get a new 026 CTS, LH2.2 didn't like the M4.4 CTS.





Next I'm going to make a EZK117 conversion. I have both 011 & 012 modules.



I'll make a hybrid dist using the lower half of the Fiat & the upper half of the Volvo (004)

Did you see that you can tune the lh 2.2 eZK also? Just have to cut the 40 pin dip chip out of the ezk and get some blank chips and a 40 pin dip programmer. I can do it. I posted a tunerpro XDF for tuning the lh 2.2 ignition bins. Early style 2.2 ezk required with the two boards inside the box. Not for the later motorolla single board 2.2 ezk. Also turbo 012 or NA 011 2.2 ezk doesn't matter same depends on the chip you burn for turbo or not either will work for either.

Cool! Did you make a thread on the EZK modding? Is there a pic of the board difference, or a date code to look for? I have two 012 & one 011 modules.

EDIT - found your thread with the zip file

Have had trouble getting rich enough AFR's under load - so I haven't pushed it. I decided to put the Bosch Yellows (200cc/20lb) used in the 960/870 NA. Warmup AFR's are more appropriate (13's), and I was able to bring the MAF voltage output down to 1.5v - warm AFR's on the WBO2 are still 14.3-15 range, & system O2 is sweeping as it should. Tomorrow I'll romp on it & see what the under load AFR's show

Raised the base FP to 50psi, now I have AFR's in 14.5-15.2 range with the engine hot & the O2 disconnected - before I had very lean AFR's if I disconnected the O2.

Hybrid Distributor is almost ready





Ready to assemble:



EZK module going here:

Is changing the rev limit self explanitory? I have put the 40 pin socket in a spare ECU - just waiting for the chips to arrive . The Fiat motor has a 7k-8k redline, so the stock rev limit is ridiculous :(

YOu can raise the rev limit in the ECU to 6.6k easily by changing the right two bits to FF which is 255 dec. The rev limiter in the EZK is not known by me where it is. If you could somehow lift the right pin on the 40 pin EZK cpu ram chip and disable the onboard ram and then wire in a 32 pin socket and use an external 27c256 chip for the program you could then use an ostrich and tunerpro and you could trace the program while running and find the rev limiter that way. Other option is learn 8 bit 8051 assembly language and decipher the code like the old Sumerian texts. Just no Vimanas or Annanuki clues involved.

Added a Volvo V70 NA 3" TB







Idle issues turned out to be caused by voltage drop at the ignition coil vBat feed.

I can't figure out how to choose the Intel P8049 chip in MiniPro for burning - do you recall what parameters to choose for setting the device?

Parts gathering for LH2.4 conversion.

951 ECU (6842115)



EZK boxes with chips - in all the boxes I looked at, it was only the older ones with phillips-head screws in the end cover that had the chip. All the torx-head screw versions had no chip.

146 ECU (3517402)



60-2 pulse wheel - manual calls for 1mm +/-.5mm offset from wheel.






Ostrich2.0



3547847 sensor & modified white block cps bracket - still have to make an adaptor plate to mount it to the motor.



Will need to do some wiring. Have to figure out how to deal with the speed signal. Need to get a late 240/740 instrument cluster & remove the circuit board that outputs the signal to pin 34

Made a bracket to locate the Crank Sensor



Not sure how to proceed with alignment of the trigger wheel - Volvo uses the trailing edge of the long tooth, then counts 15 teeth to get to TDC. This wheel has a long cutout, so not sure where to consider the trailing edge.

Been wiring the LH2.4 harness for the X1/9



Using the 760 relay 1362914



Mostly ready to tie into the vehicle harness and then add the EZK116 conversion to the 117 setup I have in place

Will be using this sender to provide the speed signal required for LH2.4.

191919149E sender 1J0973703 pigtail



Will also be running the Fiat Punto electronic speedo to replace the old cable drive unit







Feeds into the LH harness, and to the "speed healer" required to condition the signal for the speedo head.

Did you see the thread where someone got a flwheel that was similar to your trigger wheel with a long hole instead of the long no holes and it would not work in his LH 2.4 car. It turned out to be a motronic flywheel I think. Anyway if you read that ignition system post you posted about it said one long tooth.. Not one long empty area. That trigger wheel you got might not work with LH 2.4. I'm not sure on where the rev limit is in the lh2.4 EZK bin, but I do have a Non turbo lh2.4 EZK bin that has no rev limit at all if you need it.

Thanks for the heads - up. I did read that thread. Didn't relate it to my setup, however your observation is correct, thank you. I will have to remove it & add a long tooth to replace the empty area.

If you have a bin for NA with no rev limit, that would definitely be helpful I'll pm you on that, thank you.

A possible alternative for cobblers:

I was talking to Drew about the 1995 Neon he races. He switched to a PT Cruiser engine with big cams, and just installed bigger injectors with the stock Dodge computer. It tuned itself to idle and decent driveability after a few times around the neighborhood. In essence, he sized the injectors for WOT AFR, and let it get its head together with block learn.
I'm going to use the one I saved off a parts car for my Corolla, and see if that works. I have a set of 240 injectors and some 940 injectors, so I might as well start there.

Found a clutch plate from a AW55 that is the appropriate thickness



cut a piece down & braised it in place, using the inner circumference for alignment with the trough.

Just have to do the careful slot alignment on each side of the addition to match the 3º intervals







harness just about ready to go in -

i know this wasn't your question but have you considered megasquirt? all it needs for inputs are an o2 sensor, a vacuum port for the map sensor, air and coolant temp sensors, and a crank trigger. then you just wire it to the injectors. you can control ignition with it as well by adding a coil pack or just let the stock ignition take care of it. you really have found the right bunch of guys when it comes to making the bosch setup work but I like the feeling that all of my engine management sensors are fresh and i can tune it myself without too much hassle. the budget for the entire system on my car came to about $500.00. Not a small chunk of change but its really nice.
