  1. Hey guys, Having an issue with fueling that I can't seem to figure out. I'm probably just spacing out on something since it's been a while since I updated all of the input settings needed for injectors. Anyway, I'm running a Vi-PEC i88 ECU with the latest firmware and using the latest version of the Link G4+ software. The car is an Audi B5 A4 4 cylinder engine. Trigger settings are perfect. The ECU is setup using the modeled fuel equation. I had it tuned for high-z 1000cc injectors. Recently though, I installed high-z 2000cc injectors. I input the information I believe is necessar
  2. Just wanted to bump this up as I am having a similar problem. When cranking the motor, Trigger Scope function is not picking anything up. My ECU is the Vi-PEC i88 running the latest firmware and using PCLink G4+ software. Internal 3.3v is reading 3.29v. (Would cranking the motor cause this to go higher? Didn't think to check it while cranking.) Is the Trigger Scope only meant to work when the motor is running?
  3. Any specific parameters you want me to log?
  4. Alright, some updates. Went ahead and did the timing light procedure and got that all sorted out. Disabled Accel Enrichment and Overrun Fuel Cut. Car starts and idles poorly. The car is not holding the idle I would like it to (850 RPMs) when the car is warm (Car is rough idling on cold start too, but not as bad as warm idle). It stays around 1100-1200 RPMs. At this point, the motor starts running really rich and when you give it gas it starts backfiring a lot. This gets the turbo/downpipe/manifold glowing red hot in no time! While idling/trying to drive from a stop, the motor runs horri

  6. Well, I got it figured out. Trigger calibration was correct. Didn't have to play with any of that (And I'm still using the AEB 1-window trigger wheel for the cam position sensor). The issue was the base TT tune is not good enough to get my setup to start (1000cc injectors). I took the fuel table settings and fuel crank settings from the G4+ Atom sample tune (setup for 1000cc injectors). She fired right up! Idling is a little sporadic still (needs more fine tuning), but I was able to drive the car around the block and piss off my neighbors. Lol.
  7. I'll try using a 4-window trigger wheel for the cam sensor and see what happens.
  8. AEB head on 06A block. Everything else is 06A: both trigger sensors, IAT sensor, ECT sensor; cam gear is 06A (aftermarket); camshafts and valvetrain are 06A (aftermarket). MAP sensor is an AEM 7.5 bar. All sensors are brand new. The trigger wheel on the intake camshaft is the 1-window from an AEB head. I am using a non-VVT tensioner. I am aware of the timing marks on the crank gear and camshaft gear. Neither of the camshafts have actual timing marks to align to the cam caps at the back of the head. We had to manually measure the lift of the intake camshaft to find the proper timing.
  9. I have not tried much yet other than attempt to start the car. I wanted to get a log first and see what you guys think. Unfortunately, timing of the motor might not be as simple as checking it with a timing light. I have aftermarket camshafts that did not have any timing marks and required to be manually timed. I am hoping to eliminate any potential issues with the tune before I dive back into the motor and check all the timing again. The car has started and idled normal before (2 out of the 3 times I started it up back in June). Perhaps the MAP sensor was toasted when I had battery issu
  10. Okay. Had a bit of a hiatus because I needed a new battery. Also I fixed an issue with the Ethrottle so it is operating correctly with no faults. I have not really changed much in terms of the tune though, but the car is not cold starting now. Sometimes it will catch and idle rough for about 30 seconds but eventually, it stalls out. Leaving the fuel table at the base TT tune numbers is when it has the best chance of starting; if I try to pull fuel, it won't catch at all. I have attached the tune I am using for my setup and a log file of attempting to start the car a few times and it idli
  11. Scott, slightly opening the throttle body did not help the previous times when warm starting. I have adjusted some settings on the ECU now, but, unfortunately, can't start the car because sleeping neighbors. I will let you know how it goes tomorrow and get you a log file. Thanks!
  12. Thanks for the reply Scott. Yes, it is an ethrottle body. I have done TP and AP calibration. I am using the trigger timing based on what was provided in the base TT file. No trigger errors. I'll try to get some logs tomorrow. So, for the warm starting, I just need to adjust the Fuel Table 1 values at the low RPMS (approximately 0-1000) when MGP is at 0?
  13. Hey guys. The car is a 2001 Audi A4 1.8T (same as Audi TT 1.8T motor). I am using the Vi-PEC i88 ECU. I am relatively nnew to the stand-alone engine management world and am learning as I go. I started with the Audi TT base file and modified it for the sensors/injectors/etc. that I am using on my motor. It starts up on cold starts and warms up just fine. However, trying to give it throttle, the engine stalls out (even light taps). I am using a larger throttle body (80mm versus stock 60mm). I imagine I need to change some settings to compensate for this. Or, perhaps it is something else
  14. Okay. I'll set it up like that later this evening. Thanks for the help!
  15. So, the car is a 2001 Audi A4 1.8T (same motor as Audi TT 1.8T). I am running the Vi-PEC i88 ECU. I have 3 fuel pumps installed on the car (1 in the fuel tank, and 2 mounted in a surge tank). I have the 1 pump in the fuel tank powered by its own relay and the 2 pumps in the surge tank powered by a second relay (1 relay for the 2 pumps). I wired the Aux Output for the pump in the fuel tank to Aux 1 and the Aux Output for the pumps in the surge tank to Aux 2. In PCLink, I set Aux 1 and Aux 2 to Fuel Pump Relay, however, only Aux 2 is priming and running when I try to crank the motor. I hav
