I'm pretty sure both have the 4 points (22r and 22re) and the 22re dizzy connects to the 22re coil and igniter with a factory plug so it should work?
Will i have to remove the weights? or will it still work with them still connected? as the advance is controlled by the computer? does this sound right?
I'm from Melbourne but i've just moved to Canberra.

The signal rotor can rotate several degrees on the distributor shaft. The flyweights change the relationship of the signal rotor to the distributor shaft(altering timing) based on RPM. You will need to remove the weights. You should be able to reconnect the springs to hold/lock the signal rotor in place on the distributor shaft.
On the non vacume distributor, the signal rotor is fixed to the distributor shaft and ALL the timing control is performed by the ECU. This is how MS will do it also.

Ron I have noticed that MS control of the timing via VAST is not perfect, I am seeing a roughly 5 degree variance across the rev range between commanded timing and actual timing.
I am checking this by setting a fixed timing in TunerStudioMS, say 10 degrees, then using my timing light (http://www.equus.com/product_info.ph...tegory_id=1_20, it supports "advance" via strobe delay from 0 to 90 degrees) to dial in the distributor at say idle, but as I open the throttle and engine speeds increase, the timing varies slightly even with the fixed timing configured in MS.
Have you noticed this? My DIYPNP board/pin connections and tune configuration are identical to yours in your guide regarding ignition timing.

Jerry from DIYAutoTune.com here-- did you ever get the timing variance you reported corrected? It shouldn't be a problem to correct, as Matt mentioned above there could be a latency adjustment that's needed at higher RPM. I just want to make sure all is well with your setup...

I do need to pull the motor out at some point soon to diagnose an oil consumption issue.
Otherwise, the ECU portion of it is great and has been very reliable.
I did implement a PWM style IAC also, which is very nice to have on this old truck.

fellow Aussie
Hey Aussie22r,Just a fellow Aussie here, Up in sunny (not) Qld. Can you let me know how your MS goes? I converted my 22r to Re a few years back(after I got sick of playin with the 34ADM weber off a xf Falc. I used a corona avante donor,put a cressida 5mge butchered Afm on it and some major porting, decent cam and big valves, and was looking at a LCengineering setup but if you have a success, I'll definitely give it a bash.Thanks.

here is my .02
Eventually, I will do away with the AFM and might perhaps go with a direct drive coil using the hall effect pickup in the stock distributor. But for now, the stock VAST ignition system seems to be working well for my needs. And again, dead easy to get started with the DIYPNP...

I'm doing the same project now on my DOA built 22re.
Thanks, DNO

I just finished getting my DIYPNP installed with a PLX M300 wideband on my DOA HP150 22re and let me say this...even with only a no load tune; the throttle response is quicker and it feels much healthier. The only driving I've done so far is with my laptop running VE Analyze Live sitting in the passenger seat making corrections to the tune while I shuttled my baby out of the garage onto the street so I could pull my wife's Honda in. Still more tuning to do.
I started this MS journey because I had an idle miss that I couldn't find.
I ended up pulling the head and sending it back to Tim@DOA after 13 years for some freshening. He installed nitrided valves and updated the port work, and its beautiful work. Tim is a great guy to work with and he knows his stuff. I've been a customer for many years, even dropped by his shop when he was still in Cali and he made sure everything was good to go and running right.
These old motors' restrictive EFI system is 1983 computer technology.
The megasquirt gives us a way to eliminate the weak links and get the most from our engine mods and running properly. The wideband gauge is cool because you can watch as the AFR changes because Tunerstudio makes adjustments.
I believe you have to do other performance mods to see any appreciable horsepower increases with Megasquirt. I have done a few things that should help.
I gasket matched the late model upper plenum and installed a big bore throttle body. Exhaust is a thorley tri-y and 2.5" exhaust.
Head porting is one area these motors really suffer, so the aforementioned porting should really come alive along with eliminating the AFM to allow it to breath.
I will be driving this naturally aspirated for a while to see how it does but now that the computer is up to the task I will be on the lookout for some deals on turbo parts for a low boost setup. Why not...I've had this truck for 21 years and it looks and runs better than the day I bought it.

This is an old post- but still relavant I think.
Have a 1990 4runner, and as with all things it seems, mine is different.
Wanted to install the MS in the 4runner primarily for mpg's, 22re auto- I really didn't realize have bad these auto's suck.
My ecm isn't the standard one- probably a changeover year and has the trans controller inside- we tried an 88 chassis ecu bandaid but couldn't get the auto to respond- fix...5speed. Liked that so much got a deal on a relatively low mileage ret/re rebuild and am turboing the old horse- definitely not worth the money, but the cost and uglyness of new trucks in general make me want to keep the rust free 90.
Dumping the vafm, dizzy and going with LS cnp, map daddy, kkk turbo, intercooler, possible water injection, found a set of Cobalt SS supercharged Siemans Deka injectors locally.
One trick that I read about was splitting the injector harness for bank to bank- this was oe on mine.
Should be on the road in aa few weeks.

FYI Guys-- the DIYPNP is a great box, very affordable and very powerful, and we continue to sell them well and I wouldn't hesitate to recommend one to anyone that's interested in building their own PNP from a kit, build it out right and you've got a rock solid solution that'll do anything you need it to. That said, we decided to go all way for you 22r guys that might not want to build their ECU from a kit and design a full MegaSquirtPNP Gen2 system that'll drop right into your trucks. It's basically everything the DIYPNP is and a bit more, with built in Peak-N-Hold drivers allowing you to run any injector high or low impedance, as well as a much improved knock circuit allowing for noise filtering and bandpass/frequency windowing.
For those of you looking for a drop in install that literally takes less than an hour (maybe as little as 20min for the technically astute) then take a look at the new MSPNP Gen2 for the 22re. Actually, the same model fits a number of Toyotas:
1985-1990 Toyota Pickup or 4Runner with 22RE
1985-1987 Toyota Corolla AE86 with 4AGE
1985-1989 Toyota MR2 with 4AGE
1987-1989 Toyota Corolla FWD models with 4AGE
Here's a link with more info on the features, docs, software, etc:
http://megasquirtpnp.com/
And here they are in the cart: http://www.diyautotune.com/catalog/m...2re-p-503.html
As always, thanks for your support, and we'll keep the cool stuff coming!

22re Custom Turbo
I just ordered a turbo kit for my 22re (truck), shes a 93. I heard if you don't exceed 10lbs on it that you will get away without having to tune the ecu or throw a megasquirt on it. Seeing as you have a turbo thrown on yours what did you do to it to get it to run cleanly without sputtering or leaning out on fuel? Any help appreciated. Thanks

I no this is a 6month old last post , but I have a completely stock 85 4runner , 22re , 5speed , will the megasquirt gen2 , be worth getting ? will I get better MPG etc.. just wondering , I dont no anything about these .. thanks
