So I'm still messing with this problem. I got the Palm logger, and it confirms that the ECU is controlling the ISC. I'm able to turn the BISS and watch the ISC count change. I've also tried adjusting the TPS based on these readings, and that hasn't helped either.I messed with the timing a bit...
I could block the FIAV, but I also still have a spare that I could try swapping on to the car. It's probably going to have to happen at some point here. I feel like blocking the FIAV is a band-aid fix. The car is basically stock otherwise. I shouldn't have to block the FIAV to get the idle to...
Also forgot to mention that it isn't throwing any codes. It runs great except for the idle surge while rolling. Immediately stops when the vehicle speed drops to zero. Starts back up as soon as I let the car start rolling (ex. downhill roll).
Hi all.I have a 91 2.0 NT MT. I'm driving myself nuts trying to fix this idle issue. It happens both while the car is rolling in gear with the clutch pressed in, and when rolling with the clutch out with the car in neutral. It has an idle surge from 1200-1500 rpm. Worse when cold, and less so...
When I worked there, I saw a mix of Moog, TRW, 555, and no-named parts boxed up as "Duralast". It was really hit and miss. As you see, they often have multiple suppliers for the same parts, shelved at the same time.On the rare occasion, something would come through as an OEM part re-boxed...
I was going to buy another ECU off eBay to have on hand for parts, and I've now had 2 deals fall through because they opened the case and saw nothing but acid damage. At least both pulled the listings.I'll pull the ECU and start ohm-ing traces. I suspect you're correct. I didn't check all the...
So all is not well in ECU-land. I've been chasing idle issues since the fix, but for most of the time, I've been able to live with a high idle when cold, and a slightly low idle when hot. When I autox'd it, I'd just turn the BISS to set a high idle (cheap dino oil didn't like autox, and pressure...
I've seen a system similar to what you're trying to build.As a complete turbocharger replacement, it's a bit of a stretch. But you can do low RPM torque fill, where flow rates are lower, with a reasonable amount of power. The calculations posted earlier in this thread are correct concerning...
You can get the surround off from around the inside handle with just 1 screw, without removing the whole door card. I can't recall if this gives you enough room to get to the pull for the latch or not.
Also check your ground cables. If you tried to start it in gear, it may have pulled a lot of amperage and degraded a connection. The starters on these cars are fairly robust.
But for the price, the OEM knuckle kit is the way to go, even if you don't use the knuckle.

I'd say that price is the big reason. I've had some intimate experience with these turbos, and there's some really cool tech in them (and even more that's soon to come), but that tech costs money.

Update: I replaced them with pieces of aluminum flat plate. Tapped them for M8 bolts. Used a nice glob of silicone and an oring under the bolt head. Seems to work alright. I could probably have used a couple washers between the plate and the trunk to make the wing mount a tad flatter, but oh...
I ended up fitting 255/40/17 R888's on Kosei K1-TS 17x8 +35. Then fit some 255/40/17 Hankook K110's on it as well. I did roll and pull the rears. The fronts rubbed on hard bumps while turned.Fun fact. The wheels and 255's are now on my 1g NT beater on stock suspension .... it's like it's on...
I'm in need of these little fasteners. Does anybody know the part number for just these, or know where to source a set new/used?These each hold a nut for the 2 bolts that lock the wing in place once it's slid on. As you can see, mine have seen better days.
Well, it runs. Steve, I'm so glad I had your help. If you're ever in Detroit, let me know... I owe you a few beers.This is what I went for as a fix to the first issue. I now get power to the MPI relay.This was the next issue. When I scraped off the solder mask, it became clear that there...
WE HAVE A WINNER, FOLKS!!!Got the area cleaned up, and this is what I found.Otherwise, the other 2 caps werent leaking... yet.I'm guessing that running a jumper wire from the pin where IC110 connects to the main board to pin 63 is a reasonable way to fix this.
Did you ever pull the ECU and look for corrosion?I just bought enough caps to fix 10 ECUs. It drives me nuts when shipping is 3/4 of the cost, so I bought a few extras.
Oh fun. Here's a better photo of the damage that can be seen.Now for a recap of the results.Got power.Yep. Check.MPI pin 8 does NOT get pulled low. Shorting MPI pin 8 to ground makes it so the car starts and runs. However, the seized alternator and very hard to turn water pump forced me...
I did! Thanks for that awesome post.I opened the ECU and only saw the tiniest sign of what may be a cap leak. I struggled to get a good photo. It only looked to possibly affect these 3 solder joints (mainly the middle pin of that green MOFSET(?).
If I have power coming to the ECU, and it...
I guess my question is, what can cause the ECU to not have power, or to not turn on when starting the car? Can those with experience check my plan below? As long as we don't get too much rain tomorrow, I plan to run through this list to troubleshoot.It's been a while, but I'm starting to get...
You are correct that there are 4 solenoids, but they are better called:
Shift Solenoid A
Shift Solenoid B
Torque converter Lockup
Line PressureThe shift solenoids work in tandem to control what forward gear is engaged.

I've made some small programs in C++ that have deleted the columns that I don't use and modify the files with some calculated columns that I don't use in real time. But it was fairly specific.
I was curious if he had any info on how to read the shaft speed, but I'm way to busy to mess with mine right now anyway. I'd love to grab a CAN shield for my Arduino and give it a shot.
He will never see a refund.You seriously think he should get a refund for buyers regret because he didn't shop around first? LOL Do you also buy your oil there, then take it back (demanding a refund) after using it for 3,000 miles because the Walmart down the road sells it cheaper?Any...
If you could also either bend the float arm to get it to read correctly or at a potentiometer in the one wire to adjust the resistance, and therefore the reading.
Mine is sunken in a little bit. It should sit flat.Is it leaking between the glass and the seal, or the seal and the body? I pulled the glass and put a bead of clear silicone around the glass because mine was leaking between the seal and glass. Getting it to seal against a messed up body may...
I would honestly suggest that anyone looking to use EvoScan just use an Evo 8 ecu. They have better roms, more options, more patches, better all around. Switching the pins takes an hour tops.
The response I got from him last time made me feel that this would happen sooner or later.I would hope that if he does come back, that people would donate/pay him if they use his files.
When he initially "disappeared" more than a year ago (Oct '12) I ended up getting a hold of him. He said he had no plans to ever finish v2.0. He had sold his DSM before then. Unfortunately, someone else would need to pick up where he left off... all from scratch. I asked if he'd be willing to...
I've sent him an email. It took him a while to respond last time. He sold his DSM a while ago and has been out of the game since. I figured he was still making enough to keep the domain up. But like I said in the other thread, if I don't hear back from him this week and the domain is till down...
If it is gone forever, I'll supply the files. I have all the xmls and roms for the MAF and SD both regular and big maps. Let me see if I can get a hold of him and get a response one way or the other.If I don't hear back from him, I'll share the files.
This is why it wouldn't be a bad idea to cycle the vanes through the full range of motion after shut down. It would scrape any soot from the vanes before it had a chance to really build up.
