Are you using solid lifters while taking the measurements?
If you are using the normal hydraulic lifters, they will bleed down over time from the spring pressure and give you an inaccurate measurement. It sounds like that is what is happening when it changed from 0.040" to 0.047" while...
Hey,Static compression ratio is the ratio of the maximum to minimum volume in the cylinder (volume when the piston is at the bottom of the cylinder versus volume when it is at the top).This can only be changed by changing the physical components of the engine (crank throw, rod length...
Did you touch the deadtimes / latency's? I only see you mention adjusting the injector scaling.http://ceddy.us/tuning/injectors/I use the steps listed above for injector tuning.
Do you have any means of posting the tune that is currently in the car for others to look at for you? Perhaps you can get your tuner to email it to you?If not, one thing that comes to mind is there are two separate timing maps in the ECU. A high octane timing map and a low octane timing map...
Sorry to hear. More than likely its bricked. I believe its from the connector and voltage.Years ago when I first started messing with ecuflash, my laptop locked up and got blue screen of death in the middle of a flash. I shit a brick cause my car wouldn't run at all. I was able to reflash it...
Its been a long time since I did this, but I believe I replaced the ceddy mod hex and xml files with the ones in the zip file that included the emissions tables. You should compare them, just to make sure. They should be the same until the end, then there is code written that creates the...
I tried to move my wiring harness as little as possible when I switched injector #4 with #3. When I made this switch, I started the car and held the RPM's above 3,500 until it misfired. When I checked the injectors, #2 (which wasn't touched) wasn't clicking, hence my confusion.This I am not...
http://www.mandrel-bends.com/catalog/holset-hx35-turbo-outlet-flange-wg-blocked-1-2-mild-steel-2298.htmlI just bought everything from this company to make my hy35 O2 housing. Turbo flange, downpipe flange, and 2.5" pipe.
Hey guys,I am trying to diagnose and repair a misfire that I recently started having.I’m going to start by giving some background, and list the things I’ve done so far.I was cruising around one night and my car started missing. My wideband was reading “- -“ meaning lean. My car sounded...
I ended up being in the area last year and spontaneously came by the day of. The girlfriend and I had an awesome time! I'll definitely be coming again this year.
There is always this debate between flashing and ECMlink... just a breakdown:ECMlink:More upfront money: need a eprom ECU or one that can be converted to eprom (money for the ecu plus money to have it converted), plus buying the hardware and program itself.(Your 98 ECU CANNOT be converted...
"I could do as he says and wire the MAP to the MDP since I still have the wiring intact. Would I then nip out the air temp wires from the MAF plug and run the AIT while still using the factory MAF?"This is the approach I was about to do until I stumbled upon this post. I already have the MAP...
The TPS % in evoscan is usually incorrect, and needs to be set up to your car to be perfectFollow the instructions in the thread below.
http://www.dsmtuners.com/threads/how-to-calibrate-evoscan-to-read-tps.428342/The main concern is making sure the throttle plate is 100% open. Have a friend...
Just giving some basics.
AFR ratio is Air to Fuel, for example;
Parts air : Parts fuel.
"Rich" is a low number, 10.0:1, meaning 10 parts of air to 1 part fuel. (less air for the same amount of fuel)
"Lean" is a high number, 16.0:1, meaning 16 parts of air to 1 part of fuel. (more air for the...
hey guys, sorry I haven't responded in a while.I ended up taking two rear diffs (auto with LSD and manual without LSD) and made a manual with a LSD.Swapped it out with the one in the car and the noise is very minimal now. Like exactly what I would expect with the solid bushings.I have the...
When I set the base ignition timing on my car, I used the actuator feature in evoscan to set the timing. It's located in the bottom right of the program. I had to select the correct ecu but after some failed attempts, it did work.It's obvious when it does work, as you hear a change in the cars...
I couldn't remember what oil was in the diff, so I changed it out with some basic 80w90 to be sure (based on TRE's site) and the noise is the same or slightly quieter. I have two spare rear diffs, one auto w/ LSD and a manual w/o LSD. I plan on opening them up and combining them to make a manual...
Hey guys,I searched and found a few threads but none with video displaying the noise.I recently swapped my rear differential to a unknown condition USED manual LSD rear diff.At the same time, I swapped in new solid aluminum rear differential bushings. I read and understand that this will...
It's stock. I needed a new BOV anyways so I just purchased a new NGR unit, so hopefully that solves the problem. I'll update my post with results and the video once I swap it out for future reference of other users.Thanks again
Hm. I didn't even think of the BOV. I did just put on a 1g bov on because my greddy type that stripped out the adjustment screw so I replaced it.Is there a solution to fix the bov if that is the issue?
Justin,I have a 16g that is making a high pitch whine at idle. Blipping the throttle makes it go away for a second but it comes right back. If I increase the throttle steadily, it just gets louder.I'm guessing this is a sign of a turbo on its way out?Is has very little / no shaft play...
This may be a pointless question, but since the parking brake is incorporated into the inside of the rear rotors, has anyone verified that the vented rotors are dimensionally the same on the inside as the non-vented and will work? I'm looking to do this swap and wanted to ask before ordering parts.
Hmm..... I never thought to look at it like that.It wouldn't solve the problem, but it may work as a bandaid fix. If you restrict the amount of air coming in (smaller filter, pre MAF) it won't fix the creeping, but it MAY limit the amount of air the engine is pulling in, limiting your max...
Thanks, I've seen those and definitely considered getting one, but I thought I read that the need a slight angle machined on the turbo flange for block clearance and that the bolt holes were 1/2" off on the turbo flange making the ports not line up. If that specific one has reviews showing...
Awesome! Good to hear. I've been searching for a turbonetics t3 manifold and they are kinda hard to find. I found a dnp t3 manifold for $150 but I the only thing I read abou them with fitment is with a bullseye .70 t3 housing for a HX40, which is a lot larger than the HY housing correct?
Hey Justin,I currently have on my shelf a 8 blade HX35 with a .55 BEP housing. I only plan on running pump gas. I have a 2.3L and I'm looking for 450whp at least for a DD. I already have everything I need to make the HX35 bolt right on. I found a HY35 pretty cheap and I keep hearing good...
Bump cause this is something I was trying to figure out too and this helped tremendously! Maybe a moderator can change the title or make this easier to find for future use. I searched "front case bolts" and this was on the 4th page. Either way, its way old but still helps!
That is absolute pressure, it doesn't account for the atmospheric pressure (14.7 psi) so the maximum boost pressure reading is only about 29 psi of boost (43 psi-14 psi).GM MAP sensor identification information 1 bar 2 bar 3 barThat's why if you want to run 30+ psi you need a 4 bar MAP...
How are you tuning?I see you have a Wally 255, do you also have a AFPR?I ran without one forever with a wally 255, and trying to tune my injectors sucked.... It would idle fine, but under WOT is would run 11.5 when i had it set to 10.5I thought I was running out of pump so I rewired my...
I looked it up in the owners manual a while ago. They have some special name for it, but essentially it allows those two center vents to always be open, no matter what setting the vent selector is on. The top selection with the blue background means its always open, and the bottom with the white...
We need a lot more info of what you did.1) Are you using Ceddymods?
2) I see the "big maps" fuel table is open. If you do not have that rom, the tables will be like you posted. Did you look at "high octane fuel map 1 or 2"? Are they the same way?
3) Is this the image pulled from the car's...
Sorry, just checked this thread again. I learned most of the stuff I know about evoscan/ecuflash (and I still consider myself a newbie at tuning) from this youtube video series:Intro to EcuFlash - 1 of 16 (How to Tune an Evo) - YouTubeI watched it a few times to make sure I had an idea of...
For the fuel cut, I raised the load limit and left the time alone. From the factory, it is set to 200 load for 1000ms or 1 second. This means if the ECU sees more than 200 load for longer than 1 second, fuel cut will happen. If you increase the time, you are essentially shutting off a very good...
Here is a video series of ECUFlash for Evos. The program is the same for DSM's and the process is the same. Obviously the ROMS are different in the video. Its long and has a bunch of information. I watched it twice before I messed with anything to make sure I had an idea of what I was doing...
Here is a thread that I followed when I broke my alternator plug. It shows all the connections and then usually a link to the page you can buy them from. Hope this helps. I bought my replacement clip from the site and it worked perfectly. The shipping was like $5 and the part itself was like $1...
To answer your previous question, fuel cut is purely based on load and time. With ecuflash you can change these values, to either a higher value load, or a longer time.Fuel cut is the engines ecu cutting the signal to the injectors instantly after the car exceeds the predetermined load value...
http://www.dsmtuners.com/forums/articles-electrical-wiring/383190-1g-2g-aem-uego-wiring.htmlThis is what I followed, but I'm using ECUFlash. Works well for me, and I never threw a code.I'm using the rear O2. In the link below, they say that using the front O2, the AEM narrowband is a little...
That definitely crossed my mind... so dumb question but, what should the voltage be across the fuel pump? I would assume it should be the same as battery voltage correct?
Hey guys,
Just installed a brand new set of FIC 1050's. I'm tuning with EcuFlash / Ceddymods / EvoScan. I followed the procedure on Ceddy's Site:Injectors « ceddy.usI currently have my injectors scaled to 1035 in EcuFlash. (Using DSM Scaling, not Evo Scaling). I set all my fuel cells...
