i have had 3 "pro" toons done in my supra's history..... had it since may of '98. first tooner was doing the alphabet soup with piggy back hks stuff (alphabet soup= vpc, gcc, afc, bcc) so factory ecu was using knock control. remaining 2 (actually 3 if you count the email tune from the most known supra shop in the world) none of these tooners used knock control using aem v1.
i cannot directly blame them for any damage to my car but sure would of noticed it pull timing like it does now when it detects knock being it from bad gas, increased air intake temps, boost spike or whatever the case may be. after thousands spent in tuning and over 10 grand spent in motors i have decided my car will never fire without knock control turned on.

off topic..... evo boi and dc5chick need to meet up with suprastar. i have an evo and rsx as well so we would have lots to converse about.....lol

 

I'm impressed with the 2.2L now that I've tuned one and seeing how suprastar's car performs. To date he has one of the smoothest AEM controlled Evo's I've tuned or even rode in to date. It's truly an impressive car.

I only run Shell or BP from the same stations whenever possible in my car and recommend that to everyone I've tuned. It's always been good for me so I don't intend to change... except when I go e85 It's proven with one car running a thought to be a once impossible boost figure on 93 octane for 4 years, 600awhp, and now over 70,000 miles on a Buschur built engine.

Sounds good, I look forward to meeting you both

 

Heck yea! My RSX is stock ... base 5 speed =) She's nothing special but has been great to me. In fact, that's how we met 4 years ago ... cause we both had RSXs

 

I used to have an RSX Type S before my Evo. Sadly that car left with an ex... it was a sleeper and when I first got my Evo the RSX beat it.

 

mines a base model auto daily get good gas mileage car.... got an air intake and coilovers and some wheels..............nothing special either

 

So how has the car been running? Anything to report?

 

So far so good. Haven't noticed anything out of the ordinary. The 2,100rpm miss still hasn't showed up and there doesn't seam to be any misses throughout the RPM band.

For once I think I am problem free. Don't want to jinx myself but finally I think I can enjoy driving it without having to break the laptop out every second!

 

Excellent! I can't wait to have mine in my hands tonight.

Switched suprastar's Supra over to the v17 firmware last night and did some tuning on the startup and idle. The idle control was a rather large change (like it was on v16 for my car) to get it idling solid again but the initial startups had a latency on the kick-over and IAC control. At first I needed to tap the throttle for it to catch and then it idled perfect. Later in the evening when we datalogged some WOT runs to make sure no big changes from the new firmware the car started perfectly fine a few times with no user interaction. Go figure.

The rest of the map was pretty spot on after the conversion from v14. I am hoping to try AEM ECU boost control this Saturday on the car.

 

Got my box after work, they replaced the coolant resistor and the cam-crank resistor according to the notes written on the paperwork. I updated to V17 firmware and loaded my calibration. Car fired instantly and seemed good...

Sadly initial testing is not looking good for me while driving. The misfire and bouncing oddities still seem to be there. A full throttle pull has cutouts again and the wide band apparently turned off or something mid pull... like it power cycled on its own. I really cannot explain it and it makes no damn sense. The car in some ways is much worse and others it seems better, I just can't win.

I am going to have to spend some more time with it and see what the hell is going on cause I've been driving on series 1 while waiting for the series 2 to come back... Either I have some strange issue with my car that series 1 isn't affected by or series 2 is still screwed up. It's one of them near impossible things to figure out.

 

that sounds really weird .. could there be a wiring issue in the car somewhere? or something to do with the new spark tech system ?

 

Car setup been set like this for a few years. I've had the SparkTech on the car for over a year an a half so not sure. The car isn't hacke din anyway so wiring should not be the issue. I am hoping it's a car issue though and not the AEM at this point but the misfire is still at exactly 2100, 3100-3300 its like a cut in and out violent jumping. They are going to think I am crazy lol.

It's getting tested in at least one if not 2 other Evo's so I will know if its the box or car by the weekend.

 

ahh gotcha ... test cars ftw

 

Got a couple WOT pulls this morning and car seemed fine there but partial throttle cruising still has its issues...

 

This looks familiar...

Internal log of the V17 firmware doing the 3100-3300ish fueling related cutouts and jumping trying to hold a steady pace. Notice how it randomly started and then goes away with some throttle increase to stablize the car and get back to normal with a steady pace. It then started to come back again. This does not happen in with Series 1 at all.

 

Improved gas mileage with 1v17... Prior to upgrading to 1v17 I was getting about 120-125 miles on a tank of E85 city, or hwy/city. Just drove 80 highway miles on 1/4 tank of E85. Anyone else notice better gas mileage since using 1v17?

Built 2.3L stroker, HKS MIVEC cams, 80mm FP Red, MAP Rev2 intake, FIC 1450cc inj, cat delete, Full Race mani, Mil.Spec 65mm, Spoolinup COP, Speed Density, FP intake with K&N fliter, HKS DLI2, TiAL Alpha Q recirc.

About the time (one week ago) when I upgraded the firmware to 1v17, I've started having a serious oil consumption issue, but I don't think it's related to the EMS. However, I am wondering if the previous bugs from 1v12 and 1v14 could have contributed to the reason for the oil consumption issue. Any thoughts?

Other observations since moving to 1v17. Sometimes at idle (1,100 rpm) the AFR goes to 16.5-17 (did this on 1v14 as well). Other times idle AFRs are normal right about 15. This was not the case with 1v12 which was used for the initial tune. 1v17 starts are a lot better. The idle motor parking issue does seem to be resolved. However, it still want to die unless you give it some initial throttle on start. Requires revving the throttle for the first couple of seconds to prevent engine RPMs dropping too low and killing the engine. Cold start on E85 is 90% first crank... previously, it was on average 2-3 cranking attempts. Now seems more difficult to start after engine is warm.

The 3,000 RPM bucking/AFR fluctuations are 98% better. It drives like a normal car again. I had the cut out issue under heavy throttle around 5,500-6,200 RPMs with early firmware versions. Seems to be fixed with 1v17. Also with previous versions, just after starting in the morning, I had more than normal amount of white exhaust smoke... even after 5 minutes. With 1v17, no more early morning white smoke.

I am a novice with the EMS and hope the experts here can translate the issues noted above. I've made a couple logs (highway driving with a few WOT pulls in 5th and 6th gear). If anyone would like to review and assess these logs, please send me a PM.
