Hi Roman Yes I got a copy of the software last night after by haltech data viewer would not load a large file. I have a scatter xy map and it does not look like the one you show. I do not think there is a restriction it is just the way my software is reading the 4 pressure sensors. Fantastic image it gives me something to work with. Thank you. I would be interested in correspondence. I will post my image once I worked out how to use the Mega log viewer HD.

Hi R3spct What ECU model from Haltech are you using? I have used E11 and now I am using the elite 2500. Prior to this I used Kalmaker with GM ECM as used in VN Holden. I am not using the internal Map. I have connected by MAP box to an analog input. No trouble codes. This is why I built the MAP box so I can get good vacuum signals. I would agree the support is not as good as it was. I recall calling haltech Australia from the side of the road when running the E11 many years ago. However my most recent ticket remains unanswered. It may be since Haltech was acquired by Race Winning Brands inc the support enthusiasm has diminished and the forum has disappeared. kpr said In most cases with Itb's, just throw away your map sensor and tune in tps vs rpm. I disagree with this, I am running 45 TWM (Borla 2900 series) and I have a good steady with dynamic range MAP signal this provides the other axis for the BASE table.

Hi VitesseEFI I am running 4 Map sensors one for each ITB . The signals from these are processed by a PIC micro controller. This is version three hardware. I have put version one and two on a dyno. Each time learning what the Dyno operator was looking for. Before I go back to the dyno I was canvassing opinions on how the MAP signal tracks the TPS in above traces . This version is working the best and seems to mimic the single throttle the closest. I have had my 3sge Fraser on ITB for 20 years with three different ECU units; be down the air chamber box to one MAP rabbit hole; as you say not a good signal. Do you recall the dynamic range you got on the Vitesse.

Hi kpr. My question is how does this map trace compare with single throttle body? Yes I am running MAP . The set up uses 4 MAP sensors with software. Without having a single throttle body MAP to compare I was reaching out to see if this version of my software was on target. The last version ran out of vac. Thanks I take that as a YES.

I have a 3sge in my FRASER 7 with ITB. I have captured some engine data MAP, RPM, TPS SPEED. Before I return to the dynometer I am seeking opinion of the MAP signal and if it collates close to a single throttle body. The Dynamic range over the 6 km run was 18 Kpa to 92 Kpa . I have inserted two images from the trace. ECU is haltech
